REMINDER: James C.M. Hwang Seminar 3/22/12 at 10:00am in MRGN 121
by Sigo, Angie 21 Mar '12

21 Mar '12

Prof. James C.M. Hwang (hosted by Prof. Peroulis and Prof. Ye) Thursday, March 22 @ 10:00 AM - 11:30 AM - MRGN 121 Abstract: The Air Force Office of Scientific Research seeks scientific breakthroughs in solid-state materials and devices that are vital for game-changing capabilities in sub-millimeter-wave radar, ultra-wideband communications, chemical/biological/nuclear remote sensing, and ultra-high-speed on-board and front-end data processing. Such capabilities are crucial for long-term USAF C4ISR capability breakthroughs. Research proposals are sought that address high-risk, high-payoff topics having fundamental challenges that are scientifically interesting as well as technologically relevant. Currently, the research portfolio is organized in three thrusts: I) THz Electronics: These include materials and devices of covalent-bond semiconductors such as C, Si, Ge, GaAs, InP, GaN, and related compounds. The main challenges are in perfecting crystals, interfaces, transports and hetero-structures, as well as scaling to nanometer dimensions for THz operations, while maintaining adequate device characteristics such as on/off current ratio, sub-threshold turn-on slope, and breakdown voltage. Particular emphasis will be placed on approaches that can lead to high-power THz sources, such as MOSFETs or MISFETs with high-K gate stack on wide-bandgap semiconductors capable of high channel trans-conductance and low electron tunneling. II) Novel GHz Electronics: These include materials and devices of ionic-bond semiconductors such as complex oxides of transition metals, with less overlapped electron orbitals and much higher bandgaps that may relax the requirement on crystalline perfectness while delivering much higher power than covalent-bond semiconductors can. The main challenges are in understanding different mechanisms for higher-quality, larger-area, and lower-cost growth on flexible or conforming substrates, as well as in understanding doping mechanism, correlated transport, and metal-insulator transitions, especially in terms of high-concentration p-type doping and transport in oxide hetero-structures. Scaling to advance operation speed from the GHz range toward the THz range will also be explored. III) Reconfigurable Electronics: These include materials and devices of non-semiconductors that can perform multiple electronic, magnetic and optical functions. Devices based on meta-materials, artificial dielectrics, ferrites, multi-ferroics, nano-magnetics, and micro/nano electromechanical systems for reconfigurable radio-frequency front-ends will be of interest. The main challenges are in understanding the interaction between electromagnetic waves and electrons, plasmons and phonons on the nanometer scale. Additional challenges involve understanding of reproducible material preparation and approaches for devices that are compact, light, low-power-consumption, and low-cost. Bio: James C. M. Hwang is a Professor of Electrical Engineering and Director of the Compound- Semiconductor Technology Laboratory at Lehigh University. He graduated with a B.S. degree in Physics from National Taiwan University in 1970, and completed M.S. (1973) and Ph.D. (1976) studies in Materials Science at Cornell University. After twelve years of industrial experience at IBM, AT&T, GE, and GAIN, he joined Lehigh University in 1988. His current research interests include micro-electromechanical systems, radio-frequency transistors and integrated circuits, optoelectronics and bio-electromagnetics. He has been a Nanyang Professor at Nanyang Technological University in Singapore and an Advisory Professor at Shanghai Jiao Tong University, East China Normal University and University of Science and Technology of China. He co-founded GAIN and QED; the latter became a public company (IQE). He has published approximately 300 refereed technical papers and has been granted five U. S. patents. He became an IEEE Fellow in 1994. He received the CIE Outstanding Achievement Award and the IBM Faculty Award in 2007, as well as the WOCC Outstanding Contribution Award in 2011. Currently, he is on leave from Lehigh University to serve as a program manager of GHz-THz electronics at the US Air Force Office of Scientific Research. --------------------------------------- Angie Sigo Secretary, Skywalk Atrium Birck Nanotechnology Center 1205 W.

FW: XPS workshops on March 22-23 and April 12-13
by Black, Nancy Lee 20 Mar '12

20 Mar '12

Dear Colleagues, I would like to announce two XPS workshops coming on March 22-23 and April 12-13. The first workshop will focus on the Basic of X-ray Photoelectron Spectroscopy. The flier is at www.purdue.edu/discoverypark/nanotechnology/XPS/xps.php<http://www.purdue.edu/discoverypark/nanotechnology/XPS/xps.php>. The second workshop will focus on XPS data analysis using CasaXPS. Purdue has a site-lisence for this software. The flier is at www.purdue.edu/discoverypark/nanotechnology/XPS/xpslite.php<http://www.purdue.edu/discoverypark/nanotechnology/XPS/xpslite.php>. The workshops are designed for everyone who wants to use XPS and the workshops are particularly helpful for the data analysis. Unfortunately I have very limited time to help a XPS user with data analysis and the workshops can greatly accelerate your XPS analysis. The registration for both workshops is at www.conf.purdue.edu/xps<http://www.conf.purdue.edu/xps>. Please feel free to distribute this e-mail. Thank you!

REMINDER: Jeff Worne Seminar tomorrow at 12:00pm in BRK 1001
by Sigo, Angie 19 Mar '12

19 Mar '12

Jeff Worne (hosted by Dr. Yong Chen) Tomorrow, March 20 @ 12:00 PM - 1:00 PM - BRK 1001 Abstract: As new conductive materials are developed, making intelligent choices about contact metals becomes extremely important, and can strongly dominate charge transport and mobility. Further, as device size decreases, effects that are local to the metal-material interface become important considerations in device behavior. In this talk, I will discuss work on developing nanoscale transistors based on organic semiconductors and graphene, and the effects that contacts have on these materials. Bio: Jeff grew up in California where he received his undergraduate from the University of California, Irvine. He has performed his graduate work at Rice University under the supervision of Doug Natelson. His research areas include the nanoscale interaction between metals and organic semiconductors and graphene, and he is interested in further exploring the nanoscale behavior of graphene. In his spare time, he enjoys fishing, ultimate frisbee, and running. --------------------------------------- Angie Sigo Secretary, Skywalk Atrium Birck Nanotechnology Center 1205 W.

REMINDER: Dr. Debdeep Jena Seminar TODAY at 11:00am in BRK 1001
by Turner, Jaime J 07 Mar '12

07 Mar '12

Dr. Debdeep Jena Seminar March 7 @ 11:00 AM - 12:00 PM - BRK 1001 Abstract: Polarization fields are a consequence of broken symmetry in III-Nitride semiconductor heterostructures, and have remarkable consequences in the physics and device design. In the first part of the presentation, I will show how we have exploited the built-in spontaneous and piezoelectric polarization in III-Nitrides to make electronic and optical devices faster, smaller, and better. In the second part of the presentation, I will talk about another consequence of symmetry - that for scaling and low-power logic electric devices using 2D materials such as graphene, MoS2, and related thin crystals. I will present experimental data on 2D crystal transistors and phototransistors, and hopefully will be able to combine the two parts of the story into one conclusion. Bio: Debdeep Jena received the B. Tech. degree with a major in Electrical Engineering and a minor in Physics from the Indian Institute of Technology (IIT) Kanpur in 1998, and the Ph.D. degree in Electrical and Computer Engineering at the University of California, Santa Barbara (UCSB) in 2003. He joined the faculty of the department of Electrical Engineering at the University of Notre Dame in 2003. His research and teaching interests are in the MBE growth and device applications of quantum semiconductor heterostructures (currently III-V nitride semiconductors), investigation of charge transport in nanostructured semiconducting materials such as graphene, nanowires and nanocrystals, and their device applications, and in the theory of charge, heat, and spin transport in nanomaterials. He is the author on several journal publications, including articles in Science, Nature journals, Physical Review Letters, and Electron Device Letters among others. He has received two best student paper awards in 2000 and 2002 for his Ph.D. dissertation research, the NSF CAREER award in 2007, and the Joyce award for excellence in undergraduate teaching in 2010.
