Research Synopsis:

Physics underlying the electronic and photonic applications of metal-oxide and boride thin films. My research focuses on the understanding of the fundamental electrical and optical properties of thin film metal oxides and borides and the effects of structural and interfacial defects on them. Pulsed Laser Deposition is used to fabricate oxide thin films and heterostructures. A Hybrid Physical-Chemical Vapor Deposition (HPCVD) technique has been developed to deposit epitaxial boride thin films.

Technologies Impacted by Research:

Electronic and photonic devices and technologies employing superconductors, ferroelectrics, nonlinear-optical and electro-optical properties, colossal magneto-resistivity, etc.
