Abstract

Thermally stimulated current measurements were carried out on vacuum evaporated thin films of a-Se98Sb2 in the temperature range 293-328 K. Well defined TSC peaks are observed in this case. The peaks shift to higher temperatures as heating rate is increased. Using the single trap analysis, we have calculated the trap depth in the films..
