Abstract
I-V-T measurements performed on thermally evaporated CdTe films sandwiched between Aluminum electrodes have been reported over the temperature range of 220-440 K. I-V-T characteristics reveal an ohmic behavior at low biases followed by a SCLC mechanism indicating an exponential distribution of traps. The characteristic temperature of these traps has been estimated at 380K. The density of these traps and their activation energy has been found to 1.18 x 10(23) m(-3) eV(-1) and 0.5 eV respectively.
