Quantum size effects in IV-VI quantum wells

For IV-VI (PbS, PbSe, PbTe) epitaxial thin films grown by thermal evaporation on KCl (0 0 1) substrates and covered with a EuS protective layer, oscillatory dependences of the galvanomagnetic and thermoelectric properties on the IV-VI layer thickness d were observed at room temperature. The oscillations of the transport properties are believed to be associated with quantum size effects due to the electron confinement in IV-VI quantum wells. (C) 2002 Elsevier Science B.V.
