Study of Band Gap of Solid Solution ZnTe Thin Films by Prepared by Spray Pyrolysis
Abstract: Zinc telluride thin films prepared by using aqueous solution of zinc chloride and tellurium tetrachloride of 0.02 M of each at pre-heated glass substrate at 3500C. The optical band gap energy were calculated from the plot of (h) 2 verses h was of 2.26 eV. The ZnTe thin films appears to bea material which has a direct band gap. This shows that the direct allowed transition are appears to be operative. Elemental analysis was carried out on inductively coupled plasma atomic absorption and was found to be 49.01 and 54.09 of zinc and tellurium respectively.
