Robert Glosser is a professor of physics at UTD. He has worked in the area of optical properties of solids since 1967. Dr. Glosser received his Ph.D. and M.S. from the University of Chicago and his S.B. from MIT. Following his graduate work, he spent 2 years at Michelson Lab in China Lake, California and then was a Lecturer at the University of California, Santa Barbara. He then became an Assistant Professor at the University of Maryland and in 1975 came to the University of Texas at Dallas as an Associate Professor. He has mentored 25 students to their Ph.D. during his academic career.

The experimental solid-state physics at UTD is primarily concerned with optical properties of solids. We have a variety of techniques available including micro-Raman and micro-photoluminescence. There are three modulation spectroscopy apparatuses that give spectral coverage from the mid infrared through the vacuum ultraviolet. These are used to uncover the fundamental electronic and vibrational properties of solids. Materials studied recently include InGaSb, AlGaN, as well as other III-V compounds and alloys. In addition, we have studied the semiconducting silicides including FeSi 2, OsSi 2 and Ru 2Si 3. These research opportunities provide the student with hands-on experience in a variety of techniques including optical, vacuum, electronic, low-temperature and machine shop techniques.

Since 1975, this activity has provided many Ph.D. dissertation research topics from which students have gone on to positions in industry, academia and government laboratories.
