Thermoelectric properties of mechanically milled AgSbTe$_{2}$

POSTER

Abstract

AgSbTe$_{2}$ and AgBiTe$_{2}$ have gained much importance recently due to their low thermal conductivity and possible potential thermoelectric applications [1, 2]. AgSbTe$_{2}$ is the parent composition for the AgPbSb$_{18}$Te$_{20}$ high figure of merit thermoelectric alloy [3]. Crystalline size is one of the crucial parameters which affect the thermoelectric properties. In order to investigate the size effects we have ball milled AgSbTe$_{2}$ up to 4 hrs and measured the thermoelectric figure of merit, Seebeck co-efficient and thermal conductivity from 10K to 350 K for different milled samples. The results will be presented in detail. [1]. D.T. Morielli et al., Phys.Rev.Lett., 101 (2008) 035901 [2]. K. Wojciechowski et al., J. Phys.Chem.Solids., 69 (2008) 2748 [3]. K.F.
