Thermoelectric characteristics of PbS/EuS superlattices

The preparation of low-dimensional structure from binary chalcogenide compounds has been demonstrated using relatively simple method of thermal evaporation and vacuum condensation. For EuS/PbS superlattices (SL) it is shown that Seebeck coefficient and electrical conductivity increase with decreasing PbS layer thickness and reach values by several times exceeding those for one layer thick PbS film.
