BISMUTH TELLURIDE NANOWIRES THROUGH ANNEALING PROCESS, AND METHOD OF DEVELOPMENT FOR THE ENHANCEMENT OF THERMOELECTRIC EFFICIENCY OF THE SAME

摘要

PURPOSE: A supporter and a method of improving thermoelectric efficiency are provided to increase thermoelectric efficiency of a thermoelectric module consisting of a nano wire structure by improving conductivity through the crystal structure improvement of the nano wire structure. CONSTITUTION: A bismuth telluride nano wire is formed inside a porous supporter. The bismuth telluride nano wire is made of a monocrystal. The bismuth telluride nanowire is heat-treated in an inactive atmosphere. A Seeback coefficient of the bismuth telluride nano wire satisfies 57μV/K-62μV/K. The inactive atmosphere is formed with one gas selected from helium, neon, argon, krypton, xenon, or radon.
