Вплив поверхні на розсіювання носіїв струму і кінетичні ефекти в плівках n-PbTe

Based on the Fuchs-Sondheimer and Mayer models the influence of mechanisms of surface reflection of electrons on the experimental transport and thermoelectric properties of n-PbTe films on various substrates are substrates are considered. The thickness dependences of the Seebeck films based on PbTe are investigated. It is shown that for films on sital substrates mechanism of completely diffuse scattering of carriers (p≈0) are implemented and for the films obtained on fresh chips of mica chips – mixed specular-diffuse scattering mechanism of carriers (scattering coefficient p≈0,4). Keywords: size effect, thin film, lead telluride, thermoelectric properties.
