Biography

 Dr. Arnab Bhattacharya is a professor at Department of Condensed Matter Physics & Materials Science, TIFR. His work focuses on Semiconductor Optoelectronics and Nanostructures The optoelectronic devices that drive today's technological world critically depend on combining various semiconductor materials, typically of different bandgaps. These devices have many layers of materials, ranging from few-atomic layers, to a few µm in thickness. Semiconductor quantum structures – ultra-thin film, wire, or dot-like configurations of nm size are at the heart of most devices. The growth of different compound semiconductors heterojunctions is a key requirement for devices. Our lab specializes in the epitaxial growth and characterization of bulk and low-dimensional III-V semiconductors, particularly the III-Nitrides, and their use in device structures.
