Abstract
The characteristic features of nanostructuring and high thermoelectric (TE) efficiency in p-type Ag(Pb1-ySny)mSbTe 2+m, were analyzed. The search for efficient TE materials focuses on degenerate semiconductors since the underlying physics of these systems allow the coexistence of high thermopower values with high electrical conductivity to achieve high power factors. The electronic-transport properties of the compound system can be tuned primarily through carefully controlling the Pb/Sn ratio. The existence of the Pb/Sn ratio and the Ag and Sb concentration, allows for tuning of the electronic-transport properties and the identification of compositions with very high ZTs. The main advantage of this system is its exceptionally low lattice thermal conductivity.
