Surface| Summary: | Basing on The theoretical model for quantum well with infinitely high walls, thickness dependences for thermoelectric parameters of lead chalcogenides (PbTe, PbSe, PbS) nanostructures have been investigated in detail. It has been found that nonmonotonous behavior of Seebeck coefficient S with changing the well thickness in these structures takes place. Basing on the oscillations period Δdexp the approximation of theoretical d–dependencies of Seebeck coefficient S with experimental was carried out and the Fermi energy in the respective structures was determined. It has been shown that minimum guantum well width dmin, coincides with oscillations period Δdexp of Seebeck coefficient in this structure when the first energy level is equal to Fermi energy EF. |
