ALLOCATION AND PROPERTIES OF IRON STATES IN CD1-XFEXTE IN FORBIDDEN GAP ENERGY-RANGE

The use of different experimental methods (reflectivity, absorption, p hotoconductivity and cathodoluminescence) allowed us to confirm the ex istence of the deep donor-like state of iron and present allocation an d properties of the iron states in Cd1-xFexTe (0 less than or equal to x less than or equal to 0.05) at 300 K and 77 K in the forbidden gap energy range. It was concluded that the increase in width of the forbi dden gap with the change of temperature from 300 K to 77 K leads mainl y to the rise of the energy distance between the donor-like iron state (5)E and the bottom of the conduction band.
