Paper Abstract

In this paper, deposition of CdS thin films by thermal evaporation was made using high purity CdS powders as the source material. It is found that the electrical conductivity of thermal evaporated CdS thin films is very sensitive to heat. The change of surface temperature of this material leads to the significant increase in its electrical conductivity as shown by the relationship of temperature and electrical resistance. It is concluded that such a temperature-sensitive conductive behavior comes from the thermally-activated electron ejection in CdS.
