<p><P>PROBLEM TO BE SOLVED: To provide a process for producing a thermoelectric material in which the figure of merit is enhanced by employing a thermoelectric material of ultrafine particles having single nano size thereby reducing thermal conductivity significantly. <P>SOLUTION: The process for producing a thermoelectric material comprises a step for forming a deposition film by simultaneous deposition method where the thermoelectric material and a polymer are heated simultaneously and deposited while performing vapor phase mixture, a step for collecting the thermoelectric material by removing the polymer from the deposition film, and a step for sintering the collected thermoelectric material wherein a thermoelectric material having an ultrafine crystal grain size can be produced by vapor phase mixture. Furthermore, the figure of merit can be enhanced because phonon thermal conductivity is reduced sharply by phonon dispersion when the thermoelectric material is sintered. <P>COPYRIGHT: (C)2006,JPO&NCIPI</p> |
