Abstract
Zinc telluride thin films were deposited by thermal evaporation method on n-type Si substrate. The electrical properties of these films were investigated with special emphasis on the effects of a depositing temperature from 520°C to 560°C with various annealing temperatures by rapid thermal annealing (RTA) technique. Structural analysis through X-ray diffraction (XRD) was sensitive to the deposition conditions and annealing treatment. Crystallinity, carrier concentration, sheet resistance, resistivity and mobility are shown to be dependent on the thermal treatments.
