Our research is centered around understanding the effects of defects and microstructure on the physical properties of functional oxides. Using continuum level computational and experimental approaches, we try to reveal the mechanisms by which defects and interfaces impact the physical properties and at what magnitude this occurs. Such knowledge is the key to design and fabricate structures in various geometries for specific engineering applications. The applications governed by such phenomena encompass macro- and micro-scale capacitors for electric energy storage, non-volatile solid state memories, nanoscale devices, electrothermal materials and electrooptical thin films.
