Professor A.K. Ramdas, Physics
Experimental investigation of collective and localized excitations (vibrational, magnetic, and electronic) in semiconductors and their heterostructures; Raman, Brillouin, photoluminescence spectroscopy; absorption/reflectivity spectra in the visible to far infrared; magneto-optics; and modulation spectroscopy. These techniques are exploited in the context of the physics of I-VI semiconductors including diluted magnetic semiconductors and MBE-grown II-VI, III-V, and II-VI/III-V quantum well structures and novel isotopic effects in semiconductors.

Professor S. Rodriguez, Physics
Research areas include: 1) Electronic and vibrational spectra of solids, 2) Transport phenomena in solids, 3) Symmetry and the optical properties of solids in the build and their heterostructures, and 4) Phonon and electron spectra of non-periodic systems. One contribution includes a theoretical calculation of ultrasound generation in normal metals in the absence of static magnetic field.
