Ph.D., Physics, University of Kentucky
Experimental Condensed Matter Physics
Professional Interests:
Dr. Ram C. Rai's research area is experimental condensed matter physics with emphasis on low-dimensional electronic and magnetic materials, including correlated electron systems, multiferroic materials, transition metal oxides, and semiconductors via optical techniques, magneto-optical, electro-optical and transport measurements. His primary focus is in the growth and characterization of thin films of complex oxides to investigate the structural characteristics, electronic structures, spin-lattice-charge coupling processes, magnetic properties, magnetoelectric coupling, and the phase transitions in the materials.
Interested undergraduate students should contact Dr. Rai to discuss research opportunities.
