Description

Condensed Matter Physics

My group studies novel ground states and functionality in thin films and heterostructures. We exploit recent advances in atomically precise heteroepitaxy of complex oxides to develop new materials and to probe novel interface phenomena. Many of these phenomena are then incorporated into prototypical device structures. Our recent focus is on strongly correlated materials, especially new spintronic materials, as well as magnetic junction devices and magnetic logic circuits.

Nanoscience and Quantum Engineering

My group exploits atomically precise control of thin film materials synthesis and novel patterning techniques to fabricate nanostructures of correlated electron materials. Through these model systems, we develop a fundamental understanding of their behavior at the nanoscale and incorporate them into prototypical devices.
