Power consumption is a significant challenge in electronics from mobile devices to large data cen-ters. A fundamental examination of energy dissipation in such contexts can lead to orders of magnitude improvements in energy efficiency. This talk will present recent highlights learned from examining dissipation in carbon nanotubes and graphene, with consequences for many nanoelectronics. For instance, thermoelectric effects in graphene devices could be used to partial-ly mitigate the heat generated during circuit operation. In addition, data storage based on phase-change (rather than charge) with carbon nanotube electrodes has led to two orders of magnitude reduction in power dissipation. The results suggest much room to improve energy use in nanoe-lectronics, towards near-fundamental limits, through the design of geometry and materials.

Eric Pop is an Assistant Professor of Electrical and Computer Engineering (ECE) at the Univer-sity of Illinois Urbana-Champaign (UIUC). His research interests are in low-power nanoelectron-ics 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. Between 2005-2007 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) and Young Investigator Awards from the ONR (2010), NSF (2010), AFOSR (2010) and DARPA (2008). He is an IEEE Senior mem-ber and serves on the program committees of the DRC and IEDM conferences.
