Sažetak

The DC conductivity and photoconductivity of a-Se0.6Te0.4 is studied in the temperature range from 150 K to 300 K. From the temperature dependence of the dark current, the thermal activation energy of 0.14 eV was obtained. The lux-ampere characteristics at different temperatures and voltages between electrodes show that photocurrent is proportional to the flux of light to the power γ. The activation energy of the carriers from dangling-bond levels was obtained from the photocurrent variation with temperature.
