"Correlated Oxides: Materials physics and solid state devices"

Disruptive technologies often require new materials or dramatically enhanced materials properties by creating artificial structures. I will present our on-going work in the area of phase transitions in correlated oxides and their exploratory applications in solid state devices intersecting advanced communications, information processing and energy conversion. Special emphasis will be on the reversible metal-insulator transition in VO2 thin films and related heterostructures. Representative results on high speed memory, field effect switches and reconfigurable devices will be presented. I will then discuss Little RoBeep, an ambitious program to build high-performance fuel cell power sources for autonomous systems exploiting quasi-2D oxide membranes. Efforts to design instrumentation and study transport properties of free standing oxide membranes under extreme conditions will be discussed. While much of the emphasis will be on understanding device principles and the crucial role of materials synthesis, representative examples involving cross-disciplinary collaborations with applied mathematicians, physicists and electrical engineers will be highlighted.
