Biography
Professor Grein's research concentrates on the electronic and structural properties of narrow gap semiconductors with optoelectronic applications. He has worked extensively at computing nonradiative recombination and generation rates in superlattice-based infrared detectors and lasers and employs band structure engineering to optimize material properties.
