Heat expansion and electrooptic absorption of laminated semiconductors TLGaS2xSe2(1-x) (x=0,4; 0,6; 0,8)

Full text:The temperature relation of heat expansion and change of absorption spectrums under effect of an electrical field of laminated semiconductors TIGaS2xSe2(1-x)T It is revealed, that phase change in peters at replacement of atoms of a selenium by atoms of sulfur in. Is rotined, that there is a staright line a cerrallation between width of a forbidden region and coefficient of thermal expansion depending on a structure, width of a forbidden region and coefficients of thermal expansion is augmented, that is bound by change of a chemical bond between atoms in crystal lattice
