Abstract: The results of the investigation of samples of natural hole-type pyrite FeS$_2$ are presented. The regularities of variations in their electrical properties with increasing temperature in the mode of uniform heating to 635 K are established. The results obtained are analyzed in terms of the dependence of the charge carriers diffusion intensity on temperature and material characteristics.

Keywords: pyrite, non-uniform doping distribution, temperature dependence of conductivity, thermal EMF, diffusion and drift currents.
