Education:

Ph.D.May 1985 - Electrical Engineering ,Rensselaer Polytechnic Institute, Troy, New York

M. S.December 1981 - Electrical Engineering, Rensselaer Polytechnic Institute, Troy, New York

B. Tech.June 1980 - Electrical Engineering, Indian Institute of Technology, Madras, India

Ishwara B. Bhat is a Professor of Electrical, Computer and Systems Engineering Department at RPI. He received his B.S.E.E. degree from Indian Institute of Technology, India and his M.S. and Ph.D. degrees from Electrical Engineering, Rensselaer Polytechnic Institute (RPI). He has over 20 years of experience in epitaxial growth and characterization of several II-VI, III-V and IV-IV semiconductors. He was the Co-Chair of 1996 and 2000 II-VI workshops held in Las Vegas, NV and Albuquerque, NM respectively and has edited several special issues of Journal of Electronic Materials. He has served as the member of the Program Committee of several national and International Conferences. Professor Bhat has published over 75 articles in refereed journals.

Research Interest

His research interests included growth of wide band gap semiconductors (such as GaN, SiC and ZnSe) and narrow band semiconductors (such as HgCdTe, InGaSb). His accomplishments included first demonstrations of: (a) p type doping of HgCdTe by MOVPE, (b) p type doping of ZnSe by MOVPE using phenylhydrazine, and, (c) several in-situ grown IR devices in HgCdTe, and development of ELO growth process for CdTe on Si.

Prof. Bhat had over 10 multiyear contracts with various government agencies and industrial labs. His current research is focused on the growth of silicon carbide epitaxial films for use in high power, high temperature and high voltage devices, as well as the growth of InGaSb for application in multi-IR technology.
