Professor V.G.PLEKHANOV, Dr. Sci.

Experienced professional who is used to working efficiently under difficult conditions. Prefers research and has a deep knowledge of solid state physics (lattice dynamics and electronic excitation, Raman and optical spectroscopy, luminescence, anharmonicity, nonlinear optics, insulators, semiconductors, metals and polymers, and isotope effect in solid state physics; as well as isotope engineering –new isotope pure materials(Si, Ge, diamond, SiO2 etc) for computer memory, quantum computer, fiber optics and so on).
Discovered the isotope effect on exciton binding energy (Wannier-Mott exciton model), experimental evidence of self-trapped electrons and quantum diffusion of Vk center in insulators as well as the effect of the isotope disorder on the phonon and exciton states.
