The Influence of Surface on Scattering of Carriers and Kinetic Effects in n-PBTE Films
The influence of mechanisms of surface reflection of electrons on the ex-perimental 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 coeffi-cient, and...

Digital Library of Periodicals of National Academy of Sciences of Ukraine| Резюме: | The influence of mechanisms of surface reflection of electrons on the ex-perimental 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 coeffi-cient, 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 scat-tering of carriers is realized (scattering coefficient p ≈ 0.4). |
