University of Illinois at Urbana-Champaign (UIUC)AbstractRising power densities are often considered the ultimate roadblock in the evolution of nanoelectronics. From a device perspective, high power densities in small volumes are complicated by reduced thermal conductance, and the thermal impedance of material interfaces. This talk will focus on two relatively novel devices, carbon nanotubes and phase-change memory, where the electro-thermal interaction is particularly strong. Singlewall carbon nanotubes exhibit significant self-heating, showing negative differential conductance, light emission and ultimately burning in air at high bias. Phase-change memory must, by design, have high and localized power density during operation, since the state of the bit is altered thermally. Simple experiments are used to gain new insight into the Fundamental behavior of both device types. This work suggests much room for the optimization of nanoscale devices through geometry, interface and materials design. Location: Olin Hall (OHE) 122
