«The Influence of Surface on Scattering of Carriers and Kinetic Effects in n-PBTE Films»
277–288 (2017)

PACS numbers: 68.35.Ct, 68.37.Ps, 73.50.Bk, 73.50.Lw, 81.07.Bc, 84.60.Rb, 85.80.Fi

The influence of mechanisms of surface reflection of electrons on the experimental electrical transport and thermoelectric properties of n-PbTe films on various substrates are considered based on the Fuchs–Sondheimer and Mayer models. The thickness dependence of conductivity, Hall coefficient, and Seebeck coefficient of films based on PbTe are investigated. As shown, for the films on glassceramic substrates, mechanism of completely diffuse scattering of carriers (p ? 0) are implemented, and for the films obtained on fresh mica chips, mixed mechanism of specular–diffuse scattering of carriers is realized (scattering coefficient p = 0.4).

Key words: size effect, thin film, lead telluride, thermoelectric properties.
