| Abstract: | PbTe single crystals were grown by Bridgman method, its thin films have been prepared by vacuum deposition, the electrical conductivity, thermoelectric coefficient and photo conduction were measured. PbTe single crystals were reported to be a P type semiconductor, they have sensitivity to visible light, its single crystals and films have significant thermoelectrical effect. |
