BROWN UNIVERSITY Joint Materials/Solid Mechanics Seminar Series Shriram Ramanathan School of Engineering and Applied Sciences Harvard University Abstract: I will discuss solid state devices for energy conversion, energy efficient electronics and electromagnetics that could potentially be enabled by phase transitions in correlated oxides. Emphasis in this presentation will be on rutile (such as VO2) and perovskite oxides (rare earth nickelates) that display phase transitions above room temperature and structure-property relations in this context. Exotic effects with oxide heterostructures will be outlined. I will then discuss Little RoBeep, an ambitious program to build ultra-thin film solid oxide fuel cell power sources for autonomous systems exploiting quasi-2D oxide membranes. Finally, I will present on-going work to design instrumentation and study transport properties of free standing oxide membranes under extreme conditions, an area still in infancy.
