01 May '11

Dear BNC faculty, staff and students, I apologize it has taken me this long to get this welcome out to the BNC family. Without further delay, I would like to welcome Mrs. Cynthia (Cindy) Salazar. We are very fortunate to have her as our new BNC administrative assistant where she will be supporting the Director, Scientific Director and Managing Director. She will serve on the Marketing, BNC Graduate Ambassador and NanoDays team. She will also supervise all the Clerical staff in the BNC and serve as the ISI liaison. Her duties are vast, but she is very excited about the opportunity to serve in such an important role. She comes to us with 12 years of university experience where she was a program coordinator in the Department of Forestry and Natural Resources. She has extensive experience in qualtrics surveying and developing the layout for publications/newsletters. She also holds a Technical Certificate in Administrative Office Technology from Indiana Vocational Technical College. Please take some time to come by BRK 1027 to introduce yourself and welcome her to the BNC. Best regards, ~ Monica M. Cortez Allain, Ph.D. ~ ************************************************************ Monica M. Cortez Allain, Ph.D. Managing Director Birck Nanotechnology Center 1205 W.

Mask-Making Services in the BNC
by James Cooper 28 Apr '11

28 Apr '11

To: All Birck Nanotechnology Center Faculty, Staff, and Students From: Jim Cooper, Interim Director This is to inform you that Jeff Grau resigned his position at Purdue University on Monday of this week to pursue other opportunities. As most of you know, Jeff had served as our photomask and photolithography engineer for more than five years. We thank him for his past contributions and wish him well in his new endeavors. The Birck leadership is aggressively pursuing a replacement for this position. In the meantime, John Coy has agreed to provide mask and lithography services for Birck users on an interim basis. John has worked with these tools in the past, and is quickly re-learning the operation of the Electromask systems and the optical lithography tools. Mask orders should continue to be placed as normal. A decision will be made for each order whether to process the mask in-house or to send it for processing at an outside mask shop. We are working with a variety of mask shops to set up ordering and quick-turn processing. Regardless of who processes the mask, Purdue or an outside shop, the goal is to make the mask creation/procurement process transparent to Birck users. Please note the turn-around time during this period may not be as short as users have experienced in the past. We ask for your patience as we work through this organizational issue. Of course, you may contract directly with an outside mask shop if you choose. If you have any questions or suggestions, please feel free to communicate with Ron Reger, John Weaver, or myself. Thanks for your understanding and patience. --Jim

Campus High Pressure Steam Reductions for Birck Nanotechnology Center - May 11, 2011
by Jeff Goecker 26 Apr '11

26 Apr '11

Sent on behalf of Mark Voorhis: Purdue Physical Services is issuing a mandatory reduction in campus steam that is scheduled for Wednesday May 11, 2011 from 2:00pm until midnight (10 hours). With the uncertainty of this work it is unknown what effect, if any, that this will have on Birck Nanotechnology Center. If the steam pressure drops too low there is a possibility that we could lose ambient temperature and humidity control of the building (temperature to 53°) for office, laboratories, and cleanroom. The Purdue Utility Department will attempt to prevent this from happening by manually operating the steam valves in the building. But if this fails to work please plan accordingly to discontinue research activities that are critical to temperature and humidity changes. Plus plan to wear warm clothing for temperatures reaching 53°. The May 11, 2011 date was selected because most of the students on campus will have left for the summer which sharply reduces steam demand. Please let me know if there are any questions or concerns and thank you for your patience with this Physical Service request. Regards, Mark Voorhis Building Manager Purdue University Birck Nanotechnology Center Office: (765) 494-3036

Special Condensed Matter/Nanoelectronics Seminar
by Jeff Goecker 13 Apr '11

13 Apr '11

Special Condensed Matter/Nanoelectronics Seminar Friday, April 15, 2011 11:00 AM- 12:00 PM, Room 298 Physics Guangyu Xu Department of Electrical Engineering University of California, Los Angeles Variability Effects in Carbon-based Devices An often-challenged question about nanoscale devices is the variability issue resulting from either the environment or the material itself. With no exceptions, carbon-based devices usually have enhanced variability effects inherent from their large surface-volume ratios in low-dimensions. Adversely, these variabilities cause device fluctuations and limit the reliability in large-scale production. On the other hand, however, these large variability effects can be beneficial for applications in metrology, when the large fluctuations in nanoscale devices can be implemented as the ‘signal’ to achieve high sensitivities. This talk surveys the research of several typical variabilities in carbon-based devices, from the consideration of device designs in the presence of these variabilities to their implementation and potential applications as novel probing mechanisms. Discussions include the devices made of carbon nanotube, graphene and graphene nanoribbon, covering one-dimensional, two-dimensional and quasi-one-dimensional carbon-based systems. Biography:Guangyu Xu received B.S. in Fundamental Science (Mathematics and Physics) and M.S. in Electrical Engineering from Tsinghua University, China in 2003 and 2006, respectively. From 2006, he joined Prof. Kang L.Wang's group at UCLA for his Ph. D. research.

Tool missing
by Miller, Timothy J 31 Mar '11

31 Mar '11

The wrench that is used to change the blades on the Disco dicing saw is missing. It is an Allen wrench with a blue T-handle. This particular wrench was dedicated to the dicing saw to reduce worries about cross-contamination, etc. Would the person who removed the wrench please return it ASAP. Thank-you Tim

BNC Shutdown May 2-6, 2011
by Reger, Ronald K 29 Mar '11

29 Mar '11

Dear All BNC Users: The semiannual shutdown of the Birck Nanotechnology Center will take place Monday through Friday, May 2-6, 2011. The Cleanroom and Laboratories will be closed at 7:00 a.m. Monday morning. If all goes according to our plan, they will reopen at 11:00 AM Friday morning. If issues arise, they may be closed for some or all of Friday, May 6. To help us prepare for the maintenance work on the exhaust systems, please remove all material from all fume hoods prior to the shutdown. NOTE: ANY MATERIAL LEFT IN THE HOODS AT THE TIME OF SHUTDOWN WILL BE DISCARDED. The Friday startup times for the cleanroom and laboratories apply to the facility, not necessarily the equipment. During this shutdown week the process tools and equipment will also be undergoing preventative maintenance. Please check Coral for equipment startup times. Thank you for your cooperation during this important preventive maintenance shutdown. Mark Voorhis Ron Reger Steve Jurss Building Manager Process & Equipment Manager Safety Manager

IMPORTANT: Lab Chair outside of lab
by Weaver, John R 14 Mar '11

14 Mar '11

A laboratory chair was found in the atrium in a seating area, just outside of BRK 2001. It is very important that laboratory chairs NOT be moved from the laboratories. This is a health and safety issue, not just a logistics issue. Thanking you in advance for your cooperation in this matter, John John R. Weaver Facility Manager Birck Nanotechnology Center Purdue University jrweaver(a)purdue.edu<mailto:jrweaver@purdue.edu> nano.purdue.edu
