With this broad range of applications comes a diverse set of materials and processes, and occasionally certain materials used within our process tools can cause harmful levels of contamination due to particulates, outgassing, re-deposition, and chemical incompatibility. To that end we have developed a "Material and Process Compatibility" matrix showing 3 to 4 levels of allowed materials in our major systems in Lithography, Etch, Physical Vapor Deposition, and Growth/Deposition systems. These levels of allowed materials and/or substrate cleaning requirements are categorized under the areas of "Metallic Contamination," "Outgassing Contamination," "Elevated Temperature," "Backside Cleanliness," and "Special." We have carefully considered this matrix over the last several weeks, and we're now publishing it as an overlay of requirements to keep our systems clean and pristine for all users. Here is a link to the matrix: https://wiki.itap.purdue.edu/display/BNCWiki/Material+and+Process+Compatibi… In the Birck Wiki there is also a link to this matrix on each equipment page. As with any new procedure and process item we solicit your suggestions for improvements and modifications to this matrix. There is a lot of information contained in the document and we need input from the user community to ensure we have the best and most accurate information. Additionally, if you wish to use something that is outside this matrix you must contact a staff member to discuss your process requirements before running your process. Thanks for your efforts and support to keep our cleanroom tools clean and compatible with a wide range of processes for all users. The Birck Engineering Staff Birck Safety Protocols It is very gratifying to see our research community back 'in business' doing leading-edge research in our center after the long pause we all experienced this Spring. But at the same time we want to remind our entire user group of the critical importance of following the COVID safety protocols while using our facilities. If an outbreak of COVID exposures should happen at Birck there is a real possibility that we may need to close the facility again. So please read and support the following..... .....Some of our approved users are holding the doors open for others to enter the building. This may very well be a gesture of politeness to assist another, but it also can be perceived that non-approved people are entering our building with the assistance of one of our approved users. Additionally it does not allow us to have an accurate accounting of who is entering our building by evaluating card-swipe data. So everyone should swipe into Birck and not be let in by someone holding the door open. .....Face masks are required while in Birck. Approved users have been, and continue to be, strongly encouraged to bring their own face mask for their personal use while in the facility. At the entrances we have supplied quantities of disposable face masks for emergency use, but our supplies of these disposable masks are being depleted at the high rate of 300 - 400 masks per week. This rate of use seems exceptionally high when personal masks are strongly recommended. Please only take one mask from the supply, and only when you've forgotten your personal mask. ....Social distancing continues to be a challenge. This is a difficult habit to develop and groups of people have been seen clustered around a tool, or having a hallway conversation, and not adhering to the 6' spacing rule. Please continue to maintain at least 6' spacing between yourself and the nearest other person. Please stay vigilant in promoting and supporting these safety protocols. If we each do our part we will continue to stay open and conduct state-of-the-art research in our great facility. Birck Nanotechnology Center PM Shut Down Notice: October 19th - 23rd, 2020 The Birck Nanotechnology Center will be undergoing a semi-annual preventive maintenance and service shutdown October 19 through October 23, 2020.

Reminder: BNC Virtual Faculty Seminar Series TODAY @ 12:00noon. [cid:image001.jpg@01D697CE.783A4470] The BNC Virtual Faculty Seminar Series is designed to provide faculty a platform to present an overview of their research and the opportunity for collaborative discussion with other BNC faculty and researchers across six colleges and 15 academic units. Hadiseh Alaeian Assistant Professor of Electrical and Computer Engineering October 1st, 2020 | 12:00pm Join Zoom: https://purdue-edu.zoom.us/j/93857631004 Title: Atom-Nanophotonics at Low Dimensions Abstract: Combining photonic structures with thermal atomic vapors on a chip provides an efficient atom-light coupling well beyond the diffraction limit on a scalable and miniaturized platform. In this seminar, I talk about some of our results on an integrated silicon photonic chip immersed in a micro-cell with rubidium vapor and discuss the effect of transient atom-light coupling on modifying the scattering properties of the photonic devices. Moreover, I present some of our recent spectroscopy measurements of a dense atomic media coupled to the tightly confined and deep sub-wavelength mode of a photonic waveguide. Our results indicate the appearance of some collective behaviors at this pseudo-1D geometry, mediated via the single waveguide mode strongly coupled to all atoms. The talk will be concluded with some of our ideas and perspectives for using this platform for cavity QED studies and devising new schemes for investigating atom-atom interactions in more sophisticated light fields. Bio: Hadiseh Alaeian got her PhD from Stanford in 2015, studying active and non-Hermitian photonic systems, under the supervision of Jennifer Dionne and Jelena Vuckovic. After her graduation, she moved to Germany first, as a Humboldt postdoc fellow and later as a junior group leader in the group of Tilman Pfau. During that time, her research has been focused on quantum dynamics of photonic systems including their Bose-Einstein condensation, and their interaction with atoms in sub-wavelength structures. In August 2020, Hadiseh joined Purdue as an assistant professor of Electrical and Computer Engineering, and Physics and Astronomy where she will be extending her studies to the strongly interacting photon fluids using Rydberg excitons.

In the past (pre-COVID) we granted access to particular labs after a user completed BNC111 and then got permission from the faculty/scientist in charge to enter the lab. Now with each lab having its own COVID-related Standard Operating Procedure (SOP) we require each user to additionally have a SOP review and sign a document stating they will comply with the protocols and restrictions of those labs. No one is allowed to work in any lab without having this SOP review, and if a person works in a lab without the SOP review it is a serious violation of our safety protocols. If for some reason you haven't completed the SOP review(s) for the lab(s) in which you work, please contact Guy Telesnicki (gtelesni(a)purdue.edu<mailto:gtelesni@purdue.edu>) to schedule the SOP review. You can't enter the lab without it. Thanks for your understanding.

Reminder: BNC Virtual Faculty Seminar Series TODAY @ 12:00noon. [cid:image004.jpg@01D685C0.EB336F80] The BNC Virtual Faculty Seminar Series is designed to provide faculty a platform to present an overview of their research and the opportunity for collaborative discussion with other BNC faculty and researchers across six colleges and 15 academic units. Alex Ma Assistant Professor of Physics and Astronomy September 24th, 2020 | 12:00pm Join Zoom: https://purdue-edu.zoom.us/j/93857631004 Title: Superconducting circuits for quantum simulation and quantum information sciences Abstract: My research group focuses on the study of synthetic quantum materials in superconducting circuits. Superconducting circuits/qubits have recently emerged as a leading platform for quantum computation, satisfying the challenges of controllability, long coherence and strong interactions. We apply the same toolbox to the exploration of strongly correlated quantum materials made of microwave photons, and investigate the emerging quantum phases and quantum dynamics in both coherent and driven-dissipative settings. As examples, I will introduce my recent work where we experimentally demonstrated a new approach for preparing photonic many-body states in superconducting circuits using engineered dissipation. In a separate experiment, we realize a topological lattice for microwave photons using arrays of superconducting resonators and observe the dynamics of protected edge states. I will discuss other QIS topics we will explore, e.g. developing superconducting circuits/qubits-based sensors for probing materials defects and excitations. I will also mention some technical/engineering challenges in superconducting circuits, and hope to spark discussions with other teams at Birck with the relevant expertise (e.g. in material synthesis or microwave engineering). Bio: Ruichao (Alex) Ma received his B.Sc in Physics from Nanyang Technological University, Singapore in 2009. He received his Ph.D. in Physics from Harvard University in 2014, studying strongly-correlated phases of ultracold atoms in optical lattices, in the group of Markus Greiner. He was a Postdoc at the Harvard/MIT Center for Ultracold Atoms from 2014-2015 and at the James Frank Institute, University of Chicago from 2015-2019. At Chicago, he worked on creating synthetic quantum materials in superconducting circuits/qubits, in the groups of David Schuster and Jonathan Simon. Alex joined Purdue University as Assistant Professor in Department of Physics and Astronomy in August 2019. His experimental group focuses on quantum many-body physics and quantum information science using superconducting circuits, with research interests that remain at the intersection between condensed matter, AMO, and quantum information sciences.

BNC Virtual Faculty Seminar Series: Speaker - Alex Ma - Sept. 24th @ 12noon via Zoom
by Turner, Jaime J 22 Sep '20

22 Sep '20

[cid:image004.jpg@01D685C0.EB336F80] The BNC Virtual Faculty Seminar Series is designed to provide faculty a platform to present an overview of their research and the opportunity for collaborative discussion with other BNC faculty and researchers across six colleges and 15 academic units. Alex Ma Assistant Professor of Physics and Astronomy September 24th, 2020 | 12:00pm Join Zoom: https://purdue-edu.zoom.us/j/93857631004 Title: Superconducting circuits for quantum simulation and quantum information sciences Abstract: My research group focuses on the study of synthetic quantum materials in superconducting circuits. Superconducting circuits/qubits have recently emerged as a leading platform for quantum computation, satisfying the challenges of controllability, long coherence and strong interactions. We apply the same toolbox to the exploration of strongly correlated quantum materials made of microwave photons, and investigate the emerging quantum phases and quantum dynamics in both coherent and driven-dissipative settings. As examples, I will introduce my recent work where we experimentally demonstrated a new approach for preparing photonic many-body states in superconducting circuits using engineered dissipation. In a separate experiment, we realize a topological lattice for microwave photons using arrays of superconducting resonators and observe the dynamics of protected edge states. I will discuss other QIS topics we will explore, e.g. developing superconducting circuits/qubits-based sensors for probing materials defects and excitations. I will also mention some technical/engineering challenges in superconducting circuits, and hope to spark discussions with other teams at Birck with the relevant expertise (e.g. in material synthesis or microwave engineering). Bio: Ruichao (Alex) Ma received his B.Sc in Physics from Nanyang Technological University, Singapore in 2009. He received his Ph.D. in Physics from Harvard University in 2014, studying strongly-correlated phases of ultracold atoms in optical lattices, in the group of Markus Greiner. He was a Postdoc at the Harvard/MIT Center for Ultracold Atoms from 2014-2015 and at the James Frank Institute, University of Chicago from 2015-2019. At Chicago, he worked on creating synthetic quantum materials in superconducting circuits/qubits, in the groups of David Schuster and Jonathan Simon. Alex joined Purdue University as Assistant Professor in Department of Physics and Astronomy in August 2019. His experimental group focuses on quantum many-body physics and quantum information science using superconducting circuits, with research interests that remain at the intersection between condensed matter, AMO, and quantum information sciences.

[cid:image006.jpg@01D685C3.FA345960] Responding to COVID-19: Research Operations at Birck https://www.purdue.edu/discoverypark/birck/for-birck-users/covid/index.php Critical Reminder: Always Use Your Own ID for Access We recently had a disciplinary incident where one user borrowed the Birck access card from another user to work in a lab they weren't qualified for, as they had not yet reviewed and signed that lab's SOP. This is a serious violation of protocol as no user is allowed to gain access to any lab, the cleanroom, or the building on another's card. Because we're supported by recharge income, and billings are tracked to each individual student's access and use of equipment, this could be interpreted as fraudulently charging the wrong grant or account. Additionally, in this era of COVID-19, it is illegal and unsafe to work in a lab without a complete understanding of that lab's COVID restrictions and protocols. Note that students involved in this incident received sanctions from the disciplinary committee including loss of building access, and required service to the Birck community. The proper procedure if you need access to a lab is to contact the faculty or staff member in charge of the room and ask for SOP training. You must do this even if you had access prior to the COVID shutdown. For specific rooms, these can be found on a sign near the door. For specific equipment, these can be found on the Birck Wiki. The proper procedure if you lose your ID or your ID fails to open a door to which you think you should have access is to contact Mary Jo and determine if there is a problem with your card or changes have happened to the access structure. Please understand and follow this strict requirement to maintain integrity in lab use, billings, and COVID-19 safety. Thanks for your understanding, Ron Critical Reminder: Birck Safety Protocols It is very gratifying to see our research community back 'in business' doing leading-edge research in our center after the long pause we all experienced this Spring. But at the same time we want to remind our entire user group of the critical importance of following the COVID safety protocols while using our facilities. If an outbreak of COVID exposures should happen at Birck there is a real possibility that we may need to close the facility again. So please read and support the following..... .....Some of our approved users are holding the doors open for others to enter the building. This may very well be a gesture of politeness to assist another, but it also can be perceived that non-approved people are entering our building with the assistance of one of our approved users. Additionally it does not allow us to have an accurate accounting of who is entering our building by evaluating card-swipe data. So everyone should swipe into Birck and not be let in by someone holding the door open. .....Face masks are required while in Birck. Approved users have been, and continue to be, strongly encouraged to bring their own face mask for their personal use while in the facility. At the entrances we have supplied quantities of disposable face masks for emergency use, but our supplies of these disposable masks are being depleted at the high rate of 300 - 400 masks per week. This rate of use seems exceptionally high when personal masks are strongly recommended. Please only take one mask from the supply, and only when you've forgotten your personal mask. ....Social distancing continues to be a challenge. This is a difficult habit to develop and groups of people have been seen clustered around a tool, or having a hallway conversation, and not adhering to the 6' spacing rule. Please continue to maintain at least 6' spacing between yourself and the nearest other person. Please stay vigilant in promoting and supporting these safety protocols. If we each do our part we will continue to stay open and conduct state-of-the-art research in our great facility.

Birck Evaporator Safety Issue
by Reger, Ronald K 18 Sep '20

18 Sep '20

Dear All Birck cleanroom users, Yesterday we had a safety incident involving the CHA-1 evaporator. As our engineer was working on the system and lowering the bell jar the hoist failed and the bell jar came down rapidly. Thankfully he did not have any fingers or his arm inside the system so he was not injured. This is obviously a safety issue so we have taken the CHA offline until we can get it repaired. Additionally we've taking the other bell-jar evaporators offline until we can determine a mechanism for each that would prevent such an occurrence. We will be working as quickly as possible to restore them to service, but not until we have a safe mechanism to prevent this on each of them. We are consulting with other nanofabs and with internal Purdue experts for safety designs. Thanks for your understanding. Ron

Mark Voorhis Building Manager Birck Nanotechnology Center Reminders for COVID Safety The Birck center is being used much more recently due to our labs and cleanroom being opened under the new SOP restrictions. It's great to see our user community back doing leading-edge research once again! Just a reminder that we're now operating under these COVID protocols: 1. Maintain at least 6' spacing between yourself and all others 2. Wear a face mask at all times when in public places within our building 3. Honor the hallway directional arrows 4. Frequently use hand sanitizer from the dispensers located throughout the building 5. Restrict cleanroom air shower use to one person at a time 6. Restrict cleanroom gowning room occupancy to 3 persons at a time 7. Honor the staff-only hours of 6:00 am - 10:00 am on weekdays 8. Use enhanced PPE when training, including face shields in the cleanroom If we each do our part we are maximizing the chance to keep COVID exposures very low. Thanks for your great support and cooperation during these pandemic times! Please let me know if you have any questions at all. Thanks, Ron Gaining Access to Birck, Labs, and Cleanroom As a reminder as we ramp back up we have additional protocols to follow in this COVID-19 era. Users who need access only to the Birck building may contact Ron who will provide our Building SOP. Once this is reviewed then we can reinstate your badge for building access. Users who want to work in any of our labs must also have an SOP review with the specific Point of Contact for that lab, and then sign the SOP stating they will follow the safety requirements of the lab. Users who need cleanroom access must review the cleanroom SOP and sign a page stating compliance with the safety rules for the cleanroom. If you need to know who the specific POC for a lab is, or if you need to get cleanroom access, please contact Ron. rreger(a)purdue.edu<mailto:rreger@purdue.edu> Electron Microscopy Core Training Sessions We are currently scheduling all our future training sessions. If you have requested training for a BNC EM instrument through Ilab, you will receive an email this week to look for the best date to schedule your training sessions, we will start with users that requested their training on the shut-down. If you have an urgent need, contact us, we are open to accommodate our schedules so you can achieve your goals on-time. If you have members in your research group interested or looking into training, service, or assistance, please let us know as well, so we can consider everyone on time for the upcoming semester. https://wiki.itap.purdue.edu/display/BNCWiki/Electron+Microscopy Electron Microscopy Core Birck Nanotechnology Center Purdue University Postdoctoral Fellowship Program Applications [cid:image001.jpg@01D67A01.CFC860E0] Call for Postdoctoral Fellows (Flyer Attached) Deadline: November 1, 2020 KIC POSTDOCTORAL FELLOWSHIPS are high-profile, two to three year postdoctoral positions with significant independence and resources.
