STRUCTURE AND ELECTRICAL CONDUCTIVITY OF AMORPHOUS ZNTE AND CDTE

Amorphous films of ZnTe and CdTe have been prepared and studied. Electron microscope studies have shown the films to have crystallite diameters of about 25 A. A radial distribution analysis of the electron diffraction data for ZnTe shows that the first and second nearest neighbor distances are the same as in the bulk crystal and they are consistent with the basic crystalline tetrahedral units being retained in the amorphous phase. The electrical conductivity of ZnTe films has a temperature dependence which varies with the annealing temperature.
