Abstract
The room-temperature dependences of the electrical conductivity, Seebeck coefficient, and thermoelectric power factor on the thickness of thin films (d=10–400 nm) grown on mica substrates by thermal evaporation in vacuum of crystals of Bi-Sb solid solution with 9.0 at.% Sb were obtained. It was established that under increasing d the kinetic coefficients change, and in the d-dependences of the thermoelectric properties one can isolate monotonic and oscillatory components. The oscillations with a period Δd=(105±5) nm in the thickness range d=100-400 nm and with a period Δd=(8±2) nm in the range d=25-60 nm were observed. The existence of the oscillations is attributed to the quantization of the energy spectra of electrons and holes.
