NCN-NEEDS Summer School Purchasing PVD Users Seminar Survey Feedback NCN-NEEDS Summer School Spintronics: Science, Circuits, and Systems July 23 - 25, 2014 Martin Jischke Hall room 1001 For more information please visit: https://nanohub.org/groups/needs/summer_school Purchasing For a purchase request to be fully processed an explanation of why the purchase is being made MUST be filled out on the purchase request form. For the most current form please visit: https://nanohub.org/groups/bnc/File:DP_Purchase_Request.xlsx PVD Users Due to a recent power/grounding issue in bay "K" of the cleanroom, power supplies from the "Lesker and Leybold" evaporators have been damaged. These must be sent back to the factory for repair. Until the repairs are completed, we have formulated a plan to keep all users research moving in the right direction. For normal Lesker processes, the CHA will be the evaporator to use. We can shift the processes from the Leybold to the Varian or Airco. A new Sputtering system will come online the week of 05/26/14 that will be able to sputter the following materials: Ti, Au, Cu, TiO2, Al2O3, Al, Al/Si1%, Si3N4 and soon to be Ni and SiO2. For the time being, all samples will have to be submitted to Dave Lubelski for deposition. Once the evaporators are back online, training will begin for the sputtering system. Please give a minimum notice of 24 hours for sputtering source changes. Thank You, Dave Lubelski Seminar Professor Gregory B. Raupp Director, Macro Technology Works Initiative Arizona State University High Performance Flexible Electronics for Revolutionary Human-scale Systems: Thinking Outside the Box Monday, May 19th at 11:00 am in Birck 1001 For more information please visit: https://nanohub.org/groups/bnc/calendar/details/995 Survey Feedback Optical Microscopes Concerns about our two Nikon optical microscopes were recently brought to our attention and we immediately scheduled a microscope field service engineer to come in for a preventive maintenance visit. Last Friday he completed a general service on both scopes, cleaning the optics and light path, and checking the mechanical movement. A minor part for the 'north' scope has been ordered and will be installed when it arrives. Both scopes are in good working order. Also please note the Nomarski filters are available and located in the plastic container next to the microscopes. Please feel free to use these as needed, and return them to the storage box when finished. Equipment Availability We've had a number of comments from students and other users stating that it can be difficult to gain access to equipment and/or staff for training and processing. Our recent analysis shows equipment is actually being used, based on a 24/7 use model, only 20 - 30 % of the time it is available. And our equipment uptime, thanks to our engineering staff, is more than 90%. This analysis is done by looking back into Coral reports at the real usage times. So actual equipment availability is good but there is a large problem where equipment reservations are made in Coral and then not used and not cancelled. When unused reservations are not cancelled it blocks others from being able to use the tools. This situation happens for a variety of legitimate reasons . . . previous processing steps may have had issues so the samples aren't ready when planned for the reserved equipment time, additional measurement or characterization time is required prior to the next processing step, personal issues arise which cause research progress to be temporarily suspended, etc. For this fiscal year (since July 1, 2013) we have compiled a report from Coral which shows that 20 users accounted for 2554 reservations that were missed and not cancelled. Therefore there were 2554 instances since last July where Coral shows equipment blocked from use by unused reservations. We are seriously evaluating changes in our operational systems to address this issue, and we would welcome suggestions from the user community. In the meantime, please be diligent about cancelling your reservations when you realize they are not going to be used. This frees up equipment in Coral for other users and relieves the pinch points that many of you have noted. Thanks again for your inputs, and your cooperation, and we look forward to receiving your ideas on how we can address this issue. Ron

Bagwell Lecture, Federico Capasso, Wednesday May 14, 2pm Burton Morgan 121
by Shakouri, Ali 12 May '14

12 May '14

Dear Colleagues: I would like to invite you to attend the 2014 Bagwell Lecture at Burton Morgan 121 on Wednesday May 14, 2-3pm. Prof. Federico Capasso from Harvard University will talk about "New Frontiers in Optics and Photonics with Designer Electronic and Optical Materials." (see below the abstract). This lecture series was established in honor of Professor Philip F. Bagwell, who passed away in 2002. Professor Bagwell did pioneering work on mesoscopic electron transport, on semiconductor-superconductor heterojunctions, and on related devices. His interest was in the underlying physics. His quest was for fundamental understanding and his objective was to boil down complex problems down to clear descriptions and fundamental contributions. He thought deeply about problems, but also had a broad range of interests. I look forward to see you on Wednesday. Best regards, Ali Bagwell Lectures: ---------------------- 2004 Herbert Kroemer 2005 Albert Overhauser 2007 Jeff Hawkins 2009 Steven J. Hillenius 2010 Eugene A. Fitzgerald 2011 Zhores I. Alferov 2011 Wilfried Haensch 2014 Federico Capasso ----------------------- New frontiers in Optics and Photonics with Designer Electronic and Optical Materials Federico Capasso capasso(a)seas.harvard.edu<mailto:capasso@seas.harvard.edu> School of Engineering and Applied Sciences Harvard University, Cambridge, MA 02138 Wednesday, May 14, 2 - 3pm; Burton Morgan 121 The control of electrons and photons in artificially structured materials at the nanoscale by quantum and electromagnetic design has opened unique opportunities for major advances in science and technology. I will present a tutorial account of some these developments. From the design of the electronic resonances and their coupling to light in nanometer thick materials a new class of light sources (quantum cascade lasers) has emerged that now cover almost the entire infrared and far-infrared spectrum, leading to an explosive growth in applications. By structuring surfaces at the sub-wavelength with nanoscale optical resonators and nanometer thin layers "metasurfaces" have emerged that have led to powerful generalizations of the laws or reflection and refraction, new thin film interferences and new ways to generate light beams and surface optical waves with "arbitrary" wavefronts. Applications of this new "flat optics" will be presented. Finally, I will show how quantum fluctuations at the nanoscale can be designed to control macroscopic quantum electrodynamical phenomena such as attractive and repulsive Casimir forces and their interaction with micro/nanomechanical structures. Federico Capasso is the Robert Wallace Professor of Applied Physics at Harvard University, which he joined in 2003 after a 27 years career at Bell Labs where he did research, became Bell Labs Fellow and held several management positions including Vice President for Physical Research. His research has spanned basic science and applications in the areas of electronics, photonics, nanoscale science and technology including plasmonics, metasurfaces and the Casimir effect. He pioneered banstructure engineering of artificially structured materials and devices and invented the quantum cascade laser. He performed the first measurement of the repulsive Casimir force. He and his group recently discovered powerful generalizations of the laws of reflection and refraction applicable to metasurfaces and demonstrated that the latter can be used to design new planar optical components (flat optics). He is a member of the National Academy of Sciences, the National Academy of Engineering, a fellow of the American Academy of Arts and Sciences; His awards include the King Faisal International Prize for Science, the American Physical Society Arthur Schawlow Prize, the Wetherill Medal of the Franklin Institute, the IEEE Edison Medal, the SPIE Gold Medal, the European Physical Society Quantum Electronics Prize; the Berthold Leibinger Zukunftspreis (the future prize), the Julius Springer Prize for Applied Physics, the Jan Czochralski Award of the European Material Research Society for lifetime achievements in Materials Science; the IEEE D. Sarnoff Award in Electronics, the IEEE/LEOS Streifer Award, the Optical Society of America Robert Wood prize, the Rank Prize in Optoelectronics, the Material Research Society Medal, the Welker Medal, the Duddell Medal and Prize of the Institute of Physics (UK), the Newcomb Cleveland Prize of the American Association for the Advancement of Science, the "Vinci of Excellence" LMVH Prize and the New York Academy of Sciences Award.

Parking Seminar Survey Feedback Training Parking 20 parking spaces have been reserved from 10:00 am - 3:00pm on May 14th for an event in DLRC. Seminar Alexander V. Kildishev Quantum Photonics Faculty Candidate Seminar Ongoing Transformation of Computational Nanophotonics Thursday, May 15th at 9:30 am in Birck 1001 For more information please visit: https://nanohub.org/groups/bnc/calendar/details/993 Survey Feedback Vistec VB6 We have received input that the Vistec VB6 electron beam system has had maintenance and process issues. We would like to briefly summarize the approach we've been taking to resolve the problems. Vistec engineering and field service have worked diligently with us to find and fix system problems, and over the last 7 years Vistec has spent over a half-million dollars (under maintenance contracts) on parts to fix issues as they were found. That does not include the Vistec engineers' time and expenses. (It is in Vistec' s best interest to keep our machine functioning at a high level). Since the upgrade to Linux on our control system last year the software is checking parameters that the previous VAX/VMS software was incapable of checking. This significantly moved us forward to improve the machine uptime and improve the capability of the system through various machine checks and calibrations. Two system tests, a stitch test and a stability test, gave results that were within machine specification. Vistec is currently reviewing what other tests could be run to help indicate any issues that could be addressed. We have also uncovered some unreported user-generated problems. Recently we had a problem due to a user entering a value into the machine which was incorrect. It was fixed quickly and the machine was immediately returned to use. Last week a height problem was plaguing some users. A user had not followed procedure on loading of the cassette into the microscope and disturbed the height setting for all subsequent users. They did not report the problem and the next users assumed it was a VB6 problem. Once discovered the problem was fixed in 30 minutes . . . the height is fine now for all cassettes. When things aren't working correctly please report them to Bill Rowe as soon as they are noticed so that Bill can address them right away. We are still working closely with Vistec to make improvements on the VB6. Just this week they sent a new scan generator board to make improvements in our video. We are also waiting on one of their programmers to fix a problem in our software that would allow us to look at the video on our two large monitors rather that our stand-alone monitor. Information has also been exchanged with Vistec about the warnings we receive in the job calibration program for stigmation. We continue to strive to make the VB6 a machine with high uptime and very good capabilities, taking a continuous improvement approach with Vistec as our key partner in these efforts. Equipment Maintenance We have received some feedback that our process equipment suffers from low uptime and that maintenance is an issue, but nothing specific was noted. I would ask that future such inputs be a little more specific so that we may address specific process areas/equipment as they arise. Thanks again for the very constructive feedback.

Dear all, 1. Thank you all for your very useful comments in our weekly cleanroom feedback surveys over the past 6 weeks. As you may have already noticed in the last couple of weeks, we are now including actions we are taking based on your comments to every weekly Friday memo. If you don't see an action based on your response, it does not mean we have ignored it. It simply may require a longer-term action plan from our side. 2. The feedback survey is now online! Just go to https://nanohub.org/groups/bnc/users and click the survey link under operations. If you prefer a direct link, please check this one<https://purdue.qualtrics.com/SE/?SID=SV_eQbN3nYi83Hhzk9>. 3. With the end of the semester nearing, please check and identify any chemicals you will no longer need. Please see Ira for disposal. Also as a reminder chemicals are not to be stored in totes and all chemicals going onto the cleanroom need to go through Ira. This is ensure that the containers are cleanroom compatible and maintain our chemical inventories. Thank you, Dimitri ________________________________________________________________________________ Dimitrios Peroulis Professor, School of Electrical and Computer Engineering Deputy Director, Birck Nanotechnology Center Purdue University 1205 West State Street West Lafayette, IN 47907-2057 tel: (765) 494-3491, fax: (765) 494-4731 email: dperouli(a)purdue.edu<mailto:dperouli@purdue.edu> http://sites.google.com/site/peroulisteam/ ________________________________________________________________________________

Gaskell Memorial Lecture Memorial Union West Faculty Lounge Friday, May 9th at 1:00 pm For more information please visit: https://engineering.purdue.edu/MSE/AboutUs/News/Events/david-r-gaskell-memo… Shut Down Notice Preventive Maintenance Shut Down Notice May 5 - May 9 The Birck Nanotechnology Center will be undergoing a semi-annual preventive maintenance and service shutdown May 5 through May 9, 2014. Air handling systems, exhaust systems, hazardous gas delivery, and monitoring systems will be down beginning at 7 a.m. Monday, May 5 through 4 p.m. Friday, May 9. The BNC staff will be performing appropriate preventive maintenance on the process equipment at this time as well. All CLEANROOM research work will be suspended until the maintenance activities are completed and all systems are returned to normal. No one will be allowed to enter the cleanroom during this time period. In addition, the laboratory areas will also be affected by this systems maintenance. As such, all LABORATORY activities that involve exhausted hoods, vacuum systems, and/or toxic gas systems will be down beginning 7 a.m. Monday, May 5 through 4 p.m. Friday, May 9. No chemical work will be allowed during this period. At the same time Physical Facilities electrical department will be completing major modification to the isolation grounding system in all general laboratories. Outlets in the laboratory with a label starting with "N" will be powered down 8 a.m. Monday, May 5 through 4 p.m. Friday, May 9. Please move any tools requiring power from the "N" outlets to the outlets starting with "S" during the previous week. It is anticipated that the building and most process tool maintenance will be completed by the end of the day on Friday, May 9. Please check Coral for equipment status and availability. For long term research planning please refer the following future dates for our future preventive maintenance shutdowns. ? Week of October 13, 2014 ? Week of May 4, 2015 ? Week of October 12, 2015 ? Week of May 2, 2016 Thank you for your cooperation and understanding during these important preventive maintenance shutdowns. BNC Management [cid:image005.png@01CF660F.35936B30][cid:image006.png@01CF660F.35936B30] Survey Feedback A user wrote the following comments in the survey this week: "I strongly suggest that all users try to minimize the usage of supplies such as cleanroom wipes, acetone, & IPA. All too often I see people use several cleanroom wipes once and throw them away, which is a waste of money. Also keep the bench clean after finishing using. It only takes an extra five minutes." These comments are very important in that the recharge rates we calculate for cleanroom and equipment use depend directly on all costs associated with our facility and equipment . . . this is our multi-user recharge model. When more supplies are used/wasted then costs necessarily increase to cover the additional expense. By reducing waste, and using only the amount of supplies necessary for good processing, we can keep costs down which benefits all users. So please remember to use only the amount of supplies necessary to conduct processing for your samples. Also, by reusing shoe covers, veils, and other multi-use disposables we can further reduce costs. And keeping the hoods clean after using helps subsequent users to get their processes done safely and efficiently. Thank you for your support of these important issues. Ron
