"Energy Dissipation and Conversion: Examples from Graphene to Phase-Change Materials"
Dr. Eric Pop
Electrical and Computer Engineering, University of Illinois, Urbana-Champaign

Abstract
Energy dissipation and conversion are important for the design of low-power electronics and energy-conversion systems. This is also a rich domain for both fundamental discoveries as well as technological advances. This talk will present recent highlights from our studies of energy conversion in novel nanoelectronics based on graphene and phase-change materials. We have investigated both Joule heating and Peltier cooling in graphene electronics, and found that the latter could be used to partially mitigate the heat generated during circuit operation. We have also examined fundamental limits of data storage based on phase change (rather than charge or spin), achieving energy dissipation two orders of magnitude below industry state-of-the-art, approaching femtojoules per bit. The results suggest new directions to improve nanoscale energy efficiency towards fundamental limits, through the design of geometry and materials.

Biography

EPop-DeptPhotoEric Pop is an Assistant Professor of Electrical and Computer Engineering (ECE) at the University of Illinois Urbana-Champaign (UIUC).  His research interests lie at the intersection of nanoelectronics and nanoscale energy conversion systems. He received his Ph.D. in EE from Stanford (2005), the M.Eng./B.S. in EE and B.S. in Physics from MIT. Prior to joining UIUC in 2007, he did post-doctoral work at Stanford and worked at Intel on non-volatile memory. He received the Presidential Early Career (PECASE) Award from the White House (2010), Young Investigator Awards from the ONR, NSF, AFOSR and DARPA (2008-2010) and several teaching and advising awards from UIUC. He is an IEEE Senior member, a member of APS and MRS, and serves on the program committees of the APS, DRC and IEDM conferences.
