Abstract

Oscillatory behaviour was detected in the dependences of the transport properties(electrical conductivity, Hall coefficient, charge carrier mobility, Seebeckcoefficient and thermoelectric power factor) on the PbTe layer thicknessd (d = 2–200nm) in (001) KCl/PbTe/EuS quantum well (QW) structures at room temperature.The non-monotonic character of these dependences is attributed to quantum sizeeffects, which manifest themselves in PbTe QWs at sufficiently small values ofd. Thepositions of the extrema in the thickness dependences of the transport propertiesshift with changing electron concentration in PbTe QWs.
