Abstract

The production of low-resistivity, p-type CdTe thin films using the coevaporation of CdTe with Te is presented. Thin films of CdTe were deposited onto glass slides using the coevaporation of CdTe with Te with control of the source temperature. p-type thin films were produced, and the influence of the Te source temperature on the electrical and optical properties of these films was investigated. The resistivity could be reduced from 10/sup 6/ Omega cm for T/sub Te/=20 degrees C to 400 degrees C. The mobility of the films is shown to increase with an increase in T/sub Te/ to values >100 cm/sup 2/ V/sup -1/ s/sup -1/ for CdTe resistivities >
