Abstract

Abstract The total d.c. electrical conductivity of undoped PbI 2 was measured as a function of iodine potential in the region 150–300°C to determine the nature of charge carriers in PbI 2. Results indicate that PbI 2 is an ionic conductor with electron holes as the minority carriers in this temperature range. Electrical polarization experiments were also performed to determine the electron hole conductivity and concentrations, mobilities and chemical diffusion coefficients of electron holes in undoped PbI 2 between 150 and 300°C.
