4. Scientific activity of Department

For the expired years the scientific direction of Department has been connected to research of electric, optical, photoelectric and luminescent properties of the complex semiconductors received on the basis of I, III and VI groups elements. As a result of carried out longstanding researches monocrystals of layered compounds such as А³B⁶ and their solid solutions are prepared, features of electric, optical, photoelectric and luminescent properties of these crystals are investigated. In particular are in details investigated influence large-scale heterogeneous, arising in these crystals, on their electronic properties, features of interaction of laser radiation with these materials are determined, found out a number of the new physical phenomena. Further threefold analogues of these crystals are investigated, detailed information about electron and fonon processes occuring in them are received. Besides it, in the various periods physical properties of selenic rectifiers, Ge-Si and Sb₂S₃-Sb₂Se₃solid solutions, SbSI crystals are investigated and significant scientific results are prepared.

Since 70-th years of the last century, on Department carrying out researches semiconductor diod structures and heterojunctions the basis of layered compounds such as А³B⁶. It is shown, that heterojunctions, manufactured by the method of optical contact landing are well described by the Anderson model that allowed to modeling a number of the physical phenomena on their basis.

On Department intensive researches are carried out also in the field of search of new complex semiconductors. To employees of Department it is proved existence of new semiconductor compounds such as А^I₃B^III₅C^VI₉, the opportunity of formation of 45 threefold compounds in this system is shown, monocrystals of many of them are prepaared and their physical properties are investigated. The method of alloy manufacturing is offered, allowing to remove supercooling at the front crystallization for preparation of binary solid solutions with strong segregation. The preparation method of the perfect crystals of binary solid solutions with application of the having alloy made in the new way is developed, the perfect monocrystals of solid solutions Ge-Si are prepaared.

Results of research works now are used in educational process. These results are used in a number of monographies and reviews.
