The process lasted only 60min, including rapid heating for melting, boat-sliding, and cooling. Thick sheets and bars of 1mm and 2mm in thickness having preferable crystal orientation for thermoelectric conversion were successfully prepared by the process. Control of carrier concentration was attempted through addition of excess tellurium (1mass% to 10mass%) to optimize the thermoelectric properties of the material. The Hall carrier concentration was found to be decreased by addition of excess tellurium. The electrical resistivity and Seebeck coefficient varied depending on the carrier concentration. As a result, the maximum observed power factor near 300K was 4.4×10−3W/K2m, with corresponding Hall carrier concentration of 4.6×1025m−3. Thus, thermoelectric properties were controllable by addition of excess tellurium, and a large power factor was thus obtained through a simple and short process.
