FABRICATION METHOD FOR TE-BASED THERMOELECTRIC MATERIALS CONTAINING TWINS FORMED BY ADDITION OF DOPANT AND THERMOELECTRIC MATERIALS THEREBY

摘要

PURPOSE: A method for manufacturing TE system thermal conduction material forming a twin crystal by doping material addition and the thermal conduction material are provided to improve thermoelectric property by adding a doping material to the thermal conduction material and passing a heat treatment process and a rapid cooling process. CONSTITUTION: A Te system thermal conduction material and an added doping material raw material are measured respectively according to a composition ratio. The materials are put into an ample, which then is put into a furnace and is melted in the furnace. The melted raw materials are rapidly cooled and ingots are manufactured. The ingots are crushed, a hot press process is processed and a wire cutting process is performed. An ion radius of the doping material is 56-143 pm.
