Chemical Routes to Nanocrystalline Thermoelectrically Relevant AgPb_mSbTe_(m+2) Materials

摘要

Materials with compositions AgSbTe_2 and AgPb_mSbTe_(m+2) have been shown to have promising thermoelectric (TE) properties.Recently,we described the chalcogenide compounds,AgPb_m-SbTe_(m+2),or LAST-m materials (LAST for Lead Antimony Silver Tellurium),several members of which can exhibit large ZT values from approx 1.2 to approx 1.7 (LAST-10 and -18) at 700 K.
