Robert P. Devaty

Robert P. Devaty is an Associate Professor and Co-Director of Graduate Studies at the Department of Physics & Astronomy, University of Pittsburgh, within the Dietrich School. His research focuses on large bandgap semiconductors, particularly silicon carbide (SiC), employing techniques like infrared reflectance, photoluminescence, and magneto-optical spectroscopy. Current projects include detailed analysis of SiC electronic band structures and optoelectronic properties using wavelength-modulated spectroscopy. His work explores carrier lifetimes, impurities, and defects in SiC, with applications in semiconductor device development.

• Education: Not explicitly stated in text.

Research interests span semiconductor physics, optical spectroscopy, and condensed matter physics. His group investigates electronic structure, phonons, excitons, and defect dynamics in SiC. Recent studies address conduction band minima, phonon-assisted transitions, and breakdown mechanisms in SiC p-i-n structures.

Publications highlight advancements in understanding SiC’s electronic and vibrational properties. Notable contributions include resolving second conduction bands and characterizing antisite defects through anharmonic vibration studies. Experimental methods emphasize precision in low-temperature and high-magnetic-field measurements.
