Abstract

The effect of Ar laser irradiation upon ZnTe homoepitaxial growth has been investigated in low-pressure metalorganic vapor phase epitaxy. Dimethylzinc and diethyltelluride were used as source materials. The growth rate of the ZnTe layer was greatly enhanced by irradiating vertically onto the (100) substrate. Photoluminescence measurements revealed that the quality of the layer is improved by the irradiation. Diethyltelluride is effectively decomposed on the surface by the irradiation.
