Profile Summary

The theme of my research is microstructural evolution in thin film electronic materials. We focus our work on interfaces and defect structures in engineered substrates, engineered buffer layers and epitaxial compound semiconductor materials for the substrate-overlayer lattice mismatch is large.  Our research involves detailed characterization of defect microstructures and compositional homogeneity with the goal of understanding the mechanisms by which improved substrates lead to improved film quality. Our research group uses very high spatial resolution techniques for composition and structure determinations with a focus on techniques of high resolution imaging and analystical transmission and scanning transmission electron microscopy and, more recently, atom probe tomography.
