Thermoelectric figure of merit of boron phosphide

Abstract

The thermoelectric power, thermal and electrical conductivity of boron phosphide grown by chemical vapor deposition of hydrogenated compounds were measured in the temperature range from room temperature to 1000 °C and the figure of merit of boron phosphide was evaluated. The figure of merit of 8×10−4 deg−1 was obtained at 1000 °C. This is one of the largest figures of merit at 1000 °C that have ever been obtained.
