Devki N. Talwar

Indiana University of Pennsylvania


Professor Devki N. Talwar, is a Distinguished University Professor in the Physics Department at Indiana University of Pennsylvania (IUP), USA and conducts research on defects in semiconductor materials used in various electronics and opto-electronics applications. He has been with IUP for almost thirty years, and is the author of more than 135 refereed journal articles, four book chapters and more than 80 international conference presentations. He served as an Organizer in nine International Conferences organized by Materials Research Society, USA; Singapore; 5th World Congress on Materials Science and Engineering – Spain; Optics 2016; Mesoscopic Condensed Matter Physics, and Condensed Matter Physics -USA. He was invited as Honorary Guest member in Science Conclave with Nobel Laureates at IIIT-Allahabad from 2009-2014 and delivered Keynote addresses at Moscow Institute of Science and Technology and many other international conferences. His expertise in the sophisticated Green’s function technique is considered very useful for providing information on the electronic and vibrational properties of defects in semiconductors, quantum wells, and superlattices. He is recognized by the international community as a prolific researcher.

Research Interest
