Abstract
The theoretical variation of the thermoelectric figure of merit of heavily doped polycrystalline hot-pressed germanium-silicon alloys is investigated as a function of carrier concentration. It is shown that in a material with a finite grain size (typically 10−4 m to 10−8 m) the figure of merit is increased and that the optimum doping level is reduced over that which would be required in a single-crystal alloy.Keywords
