QUANTUM-DIMENSIONAL EFFECTS IN THERMOELECTRIC CHARACTERISTICS OF LEAD CHALCOGENIDES NANOSTRUCTURES

QUANTUM-DIMENSIONAL EFFECTS IN THERMOELECTRIC CHARACTERISTICS OF LEAD CHALCOGENIDES NANOSTRUCTURES

On the basis of theoretical model of quantum well (QW) with infinitely high walls it was investigated thermoelectric parameters depending on the thickness of the layer of nanostructures IV-VI (PbS, PbSe, PbTe) in the approximation of changing Fermi energy. There have been shown that the dependences...
