Abstract

We report microstructures and thermoelectric properties of In4Se3 thermoelectric materials. In4Se3 powder was synthesized by conventional melting process in evacuated quartz ampoules and sintering of In4Se3 was performed by spark plasma method at various sintering temperature. The microstructure and density of the sintered body of In4Se3 were strongly dependent on the sintering temperature. Thermoelectric properties, such as electrical conductivity, Seebeck coefficient and thermal conductivity, were also characterized and the effects of the sintering condition on the thermoelectric properties were investigated.
