FW: Happy Thanksgiving, Announcement
by Black, Nancy Lee 24 Nov '21

24 Nov '21

Dear BNC Community, Many of us have worked directly or indirectly with Ali throughout his 10 years of directorship and witnessed how Birck becomes a wider multi-disciplinary community. His contributions are beyond words. We sincerely thank Ali for all that he has done for Birck and the broader community and wish him greater success in his next leadership role. We are planning a holiday celebration in December (announcement will be sent after the Thanksgiving holiday) and will have a dedicated session to celebrate Ali’s decade-long contribution to Birck. Please join us. Birck will be under an interim directorship for some time, which will be officially announced by the EVPRP office. Please let the Birck leadership team know if you have any questions or comments. Happy Thanksgiving and wish everyone enjoy a nice holiday break! Zhihong Zhihong Chen Professor of Electrical and Computer Engineering Birck Associate Director for Research Birck Nanotechnology Center Purdue University 1205 West State Street West Lafayette, IN 47907-2057 Tel: (765)494-0772<tel:%28765%29494-0772> Fax: (765)496-8299<tel:%28765%29496-8299> Email: zhchen(a)purdue.edu<mailto:zhchen@purdue.edu> From: BNC-all <bnc-all-bounces(a)ecn.purdue.edu<mailto:bnc-all-bounces@ecn.purdue.edu>> on behalf of "Shakouri, Ali" <shakouri(a)purdue.edu<mailto:shakouri@purdue.edu>> Date: Wednesday, November 24, 2021 at 1:52 PM To: "bnc-all(a)ecn.purdue.edu<mailto:bnc-all@ecn.purdue.edu>" <bnc-all(a)ecn.purdue.edu<mailto:bnc-all@ecn.purdue.edu>> Subject: [BNC-all] Happy Thanksgiving, Announcement Dear All, I wish you and your family a Happy Thanksgiving. We had our first in-person Birck staff event after COVID with the Thanksgiving lunch last week. I was delighted to thank our outstanding staff who work behind the scenes for the smooth operation of the center. Covid and major changes in society in the last two years make us think about many of our assumptions. However, one thing is certain. The value of the organization is in people and how a shared vision and a common goal of research excellence and societal impact can make a whole which is much larger than individual parts. I will be transitioning out of Birck leadership after ten years at the end of December. It has been a real privilege and honor to work with our outstanding students, staff and faculty. The vision and hard work of Jim Cooper, Dick Schwartz, Tim Sands, the founding faculty and dedicated staff have created a really unique interdisciplinary shared research environment that is rare in universities. Birck faculty have been able to increase the research funds from $15-20M/year a decade ago to more than $30M/year while we reduced our research overhead (subsidy) to operate the recharge centers from 45-50% (which was in par with top nano centers in US) to ~35% just before COVID. Last year has been difficult financially, but our faculty have brought record grants and the operation is ramping up steadily. Beyond supporting existing faculty, my major focus through cluster hires, preeminent teams and regular meetings with academic units has been the broadening of the Birck mission beyond nanoelectronics and quantum to ag, manufacturing, computer science/AI, biomedical/ vet med, pharmacy, physics, chemistry, and polytechnic. The SMART /WHIN projects have helped to align Birck’s mission to the mission of the original land-grant university by working closely with the community and elected officials in the ten surrounding counties. Purdue 2050, Conference of the Future, which was part of Purdue’s 150th anniversary events, helped us to connect to College of Liberal Arts, Honors College and Krannert. Some of this engagement is continuing through Neil Dilley’s great efforts in storytelling competition and new posters throughout the center. Birck strategic leadership team which included our managers (Zhihong Chen, Ron Reger, Mark Voorhis, Steve Jurss, Marcie Britton and Jaime Turner) as well as Neil, Tracy Hudson and Justin Wirth worked hard to streamline many of our operations and help improve the Birck culture. Outstanding initiatives by NSAC (e.g. during Covid-19 social distancing which was particularly hard for our students) are lessons that Birck’s main impact is our students and postdocs and we need to find ways to better engage them to shape our center. In the last ten years, we have housed 20 new faculty from 8 academic units from 5 colleges to setup part or all of their research operations at the Birck Center. This required renovating or re-assigning >13,000 sq. ft. of cleanroom and lab space. Since 2012, we have invested ~$18M in new shared tools. About 1/3 of this is from our recurring facility and equipment replacement budget and 2/3 was through competing in internal Purdue competition (Engineering Preeminent Teams, EVPRP Equipment grants), as well as startup package of faculty who believe in Birck's shared labs. Several faculty have also brought equipment through external grants (MRI and DURIP). During 2019-2020, we did a comprehensive planning for Birck 2.0 and the future needs for state-of-the-art nanofabrication and nanocharacterization at Purdue. The process was one-year long, engaged 35 faculty, 12 Department Heads, 5 Associate Deans for Research and 3 Deans. This resulted in a comprehensive 140-page report about facility needs and potential future centers of excellence. Some of this blueprint is the foundation of faculty initiatives in collaboration with PRF (Discovery Park District) that will hopefully leverage major federal funding through USICA (CHIPS and Endless Frontier Acts) and other sources. Moving forward, my recommendation is that Birck will be stronger when more faculty, students and staff engage and take ownership in our operation and future vision activities. This is critical for a vibrant center. I plan to focus on SMART industry consortium, AI in Community initiative as well as the commercialization of a new semiconductor characterization technology. We just received an NSF ERC Planning grant focused on AI in Manufacturing that will hopefully help us keep the momentum and create a new center of excellence. I would like to acknowledge the outstanding work of other previous and current Associate, Deputy and Scientific Directors: Zhihong Chen, Sunil Bhave, Yong Chen, Dana Weinstein, Dimitri Peroulis, Vlad Shalaev and Joerg Appenzeller as well as our Faculty Leadership Council (also including Rakesh Agrawal, Sasha Boltasseva, Miko Cakmak, Carol Handwerker, Mike Ladisch, Sophie Lelievre, Mark Lundstrom, Mike Manfra, Lisa Mauer, Jeff Rhoads, Haiyan Wang, and Alex Wei) who have played key roles to co-lead the center and help with several strategic initiatives. Thanks for everybody’s support over the years. It is an honor to be part of the Birck family. Best regards, Ali

Season's Greetings
by Shakouri, Ali 24 Nov '21

24 Nov '21

Dear All, As the year is coming to close, we reflect on unprecedented events that have impacted all of our lives. This is a difficult situation with self isolation and physical distancing, especially for many of our international students and researchers who are thousands of miles away from their families. There are some who have been personally impacted with the loss of family members and millions who are in economic hardship. During these difficult times, we appreciate unique gifts and contributions from each member of our community. We are fortunate to have dedicated students, staff and faculty who went out of their ways and regular responsibilities to help each other. We managed to keep Birck operational for critical research between April and June. Our dedicated staff and faculty developed standard operating procedures for all labs and cleanroom that are shared by more than 500 users across campus. Thanks to everybody who has been careful and extra vigilant, we had a smooth operation during the Fall semester. We would like to thank everybody's great contributions and hope you will have safe and healthy end of the year holidays and best wishes for the New Year 2021. Sincerely, Ali, Zhihong and Sunil [cid:image002.png@01D6D3A2.91AE72E0]

The university is officially closed during this time and reopens on Monday January 3. As we have done in past years, the Birck Nanotechnology Center will remain available for research but will be unstaffed and hazardous gasses will be unavailable. As always if you plan to do any work over the recess please follow all applicable Protect Purdue protocols. Following is a description of the Birck center during this period of university closure: 1. All labs and cleanroom will be open. 2. All hazardous gases will be unavailable. 3. HF, BOE, and TMAH chemical processing will be allowed as long as a buddy is present. 4. Precursors for ALD systems will be available. 5. No shipping or receiving is being done at any building on campus. 6. The custodians will not be working so restrooms will not be maintained, and sanitation of touch surfaces will not be done. * We encourage users to keep the facility clean and be extra vigilant about the hygiene and COVID risks. 7. A few engineering and building staff may walk through occasionally for major issues but availability will be very limited and could be impacted due to COVID restrictions. * Faculty and senior researchers are encouraged to be more proactive (e.g. occasional walk throughs checking the labs where there is ongoing research). Email Birck management if you notice anything. Since there will be limited staff support during this winter recess the research groups are strongly encouraged to accomplish as much processing as possible before gases are turned off on Dec. 22. See the following for more detailed information (this will be up on the BNC Wiki): 2021-12-23 to 2022-01-03: Reduced Holiday Operations Due to Purdue’s Winter Recess hazardous gases will be unavailable from 3:30 PM Wednesday, December 22 until 8:00 AM on Monday, Jan 3rd. Lab work may otherwise proceed, though any fume hood work must be done with someone else present in the same laboratory or cleanroom bay (the “buddy” system). Please note the following changes to our normal operation: * ALD sources will remain available * Unavailable gases: * Ammonia (NH3) * Boron trichloride (BCl3) * Chlorine (Cl2) * Dichlorosilane (H2Cl2Si) * Hydrogen (H2) * Hydrogen Sulfide (H2S) * Krypton Fluoride (KrF) * Methane (CH4) * Nitric Oxide (NO) * Silane (SiH4) * Trichlorosilane (HCl3Si) * Tools affected: * Reduced capability: * PVD Nitride Sputtering System (NH3 unavailable) * Tube 1 Clean Ox (H2 unavailable, dry oxidation only) * Tube 4 Field OX (H2 unavailable, dry oxidation only) * Tube 7 General Oxidation (H2 unavailable, dry oxidation only) * Panasonic (Cl2 and BCl3 unavailable) * Plasma-Therm Apex SLR ICP RIE Etcher (H2, Cl2 and BCl3 unavailable) * Shutdown: * Axic PECVD (NH3 & SiH4 unavailable) * Easy Tube 3000 DVD (CH4 unavailable) * Epigress (SiH4 unavailable) * H2S CVD (H2S & H2 unavailable) * Nitric Oxide Anneal (NO unavailable) * Plasma-Therm Apex SLR HDPCVD (SiH4 unavailable) * Tube 2 Nitride (NH3 and HCl3Si unavailable) * Tube 3 LTO (SiH4 unavailable) * Tube 6 Polysilicon (SiH4 unavailable) * Work with highly dermally toxic materials (25% TMAH, BOE, HF) ABSOLUTELY requires a buddy within eyesight at all times. * Custodial staff will not be working. * There will be limited restocking of shared use supplies. * There will be limited availability of engineering staff to answer questions or repair down equipment. * On metallization tools sources will not be changed and depositions must be < 200 nm.

Series information: Our series is aimed at active researchers and educators and designed to introduce practical skills with online, hands-on activities that participants will be able to incorporate in their own work. Hands-on activities will use nanoHUB cloud computing resources, negating the need to download or install any software. All that is required of the audience is an internet connection and an hour to spare for the demonstration. After the training sessions, you will be able to continue using nanoHUB for research or education. Recordings and associated materials from prior workshops can be found at the workshop webpage: https://nanohub.org/groups/ml/handsontraining<https://click.mail.nanohub.org/?qs=fa5d19fdba110be3328ac7c0e6aa1c23ed02fcba…> Register soon as seats are limited. Date/Time: Wednesday, November 17, 2021 / 1:00 PM – 2:00 PM EST Title: Integrating Machine Learning with a Genetic Algorithm for Materials Exploration Presenter: Joe D. Kern, Georgia Institute of Technology, Ramprasad Group Register for this workshop here<https://click.mail.nanohub.org/?qs=fa5d19fdba110be31df082c3e47a7f7022739f4c…> Abstract: The genetic algorithm is a computer algorithm inspired by nature: selecting parents of a generation via some fitness function, crossing-over the parent genes (reproduction), and randomly mutating the genes of the children. In this talk, we will explore how this algorithm can be used for materials discovery by: 1. Generating swift material property prediction using machine learning (ML) 2. Creating an algorithm to design new materials from combinations of prior ones 3. Integrating the ML property predictors with the design algorithm to discover new materials PolyGA, an implementation of the genetic algorithm for the polymer domain, will be used as the basis for this exploration. Bio: Joe D Kern is a Materials Science and Engineering graduate student at the Georgia Institute of Technology in the Ramprasad Group. Prior to graduate school, he dual majored in Materials Science and Computer Science at the University of Wisconsin – Madison and spent six years in the Minnesota National Guard as an Arabic Linguist. His research involves utilizing computational techniques, such as genetic algorithms and machine learning, to expedite materials discovery in the polymer chemical space.
