The effective role of temperature in improving the electrical conductivity and thermopower of n-PbTe films

Abstract

This paper discusses the effective role of temperature in improving the electrical conductivity and thermoelectric power of n-PbTe films obtained by high-temperature evaporation. It has been established that an increase in the substrate temperature to 350-370 0С leads to an increase in thermopower and electrical conductivity due to an increase in the diffusion process, leading to an increase in blocks. It is found that the thermoelectric parameters strongly depend on the film thickness.
