Abstract :
This research describes the thermopower and electric conductivity of CdTe films produced using thermal evaporation technology; the energy activation value of this electrical and thermoelectrically properties are estimated. CdTe sheets have an electrical resistance of about (107. cm). Conductivity was studied, and it was found that the electrical conductivity increased with temperature. At low temperatures, there are two values of activation energy (Ea1 = 0.337eV ) because of this dependence, but at high temperatures, (Ea2 = 0.702eV ) is the only value of activation energy. The Seebeck coefficient (thermopower) was researched to find that it was temperature-dependent, and it was found that, as the temperature increased, the Seebeck coefficient decreased. The experiment results on thermoelectric power were summarized in a two-paragraph statement. The activation energy was measured to be (ES = 0.561eV ), and the CdTe film was shown to be p-type conductive.
