摘要：
The compositional dependence of electrical properties such as thermoelectric power, carrier concentration and conductivity, of two-source vacuum evaporated Cd1-xZnxTe polycrystalline thin films (0 less than or equal to x less than or equal to 1) were investigated. The temperature dependence of conductivity was studied in the range 100-400 K and the films were found to exhibit two activation energies. Analysis of the activation energy in the low-temperature region led to the conclusion that the electrical conduction might be due to charge carriers in fully ionized trap states of the partially depleted grains, while the conduction in the high-temperature region might be due to thermionic emission of charge carriers from grains.
