Abstract

The present paper reports the thermally stimulated current measurements in vacuum evaporated thin films of a- Se60Te20Ge20. This composition is selected based on the highest photosensitivity at this composition in a- Se80-xTe20Gex series. Well defined TSC peaks are observed in this case. The peaks shift to higher temperatures as heating rate is increased. Trap depth has been calculated from the heating rate dependence of peak temperature and also from the heating rate dependence of current at the peak temperature..

Keywords

Thermally stimulated currents, Chalcogenide glasses, Amorphous thin films.
