Quantum size effects in IV–VI quantum wells

For IV–VI (PbS, PbSe, PbTe) epitaxial thin films grown by thermal evaporation on KCl (001) 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.
