摘要: The recent energy demands affected by the dilution of conventional resources and growing awareness environmental considerations had motivated many researchers to seek for novel renewable conversion methods. Thermoelectric direct thermal into electrical energies is such a method, in which common compositions include IV-VI semiconducting compounds (e.g., PbTe SnTe) their alloys. For approaching practical thermoelectric devices, current research focused on electronic optimization off-stoichiometric p-type PbxSn1−xTe alloys tuning Bi2Te3 doping and/or SnTe alloying levels, while avoiding less mechanically favorable Na dopant. It was shown that upon doping/alloying, higher ZTs, compared those previously reported undoped Pb0.5Sn0.5Te alloy, were obtained at temperatures lower than 210–340 °C, depending exact doping/alloying level. demonstrated optimal grading carrier concentration, maximal e...
