Basic scientific achievements Mechanisms have been established in transport phenomena, various non-equilibrium electron processes, origin type of conductivity, the influence of different external factors on the electrical, optical, thermal and mechanical properties of amorphous, crystalline and liquid selenium.

It is shown that anomaly in the properties of selenium are associated with the presence of impurities of oxygen, it is determined the quantity and condition of the latter in selenium proposed by the special unit for cleaning of selenium from oxygen.

The obtained results have made to specifically manage the properties of selenium and make recommendations to enhance the performance of selenium converters. And in the former Soviet Union for the manufacture of new effective selenium converters was organized special production in the sityYoshkar-Ola.

Recent years studied electronic phenomena in chalcogenide glassy semiconductors on the basis of selenium.

The developed technology of making of crystallization sustainable binary (Se-As; Se-Te) and triple (As-Se-Te; As-Se-S) chalcogenide vitreous semiconductors systems, the introduction of impurities of Halogens and rare earth elements reached purposeful change their electronic properties and the enlargement of field of application of these materials in practice.

As a result of comprehensive research: the impact of impurities Halogens drift mobility, injection currents, photoconductivity and optical properties of the chalcogenide glasses was made the target of vidicons; the influence of chemical composition and doping on Raman light scattering, x-ray diffraction, linear and nonlinear refractive indices. And optical parameters by the method of ellipsometry were proposed transparent in the near and middle infrared ranges of materials for waveguides.
