Chemistry, Physics and Technology of Surface| Zusammenfassung: | Dependences of the structural characteristics and electrical properties of thin films of solid solutions PbTe-Bi2Te3containing 1, 3, 5 mоl. % Bi2Te3, deposited in open vacuum for fresh chips (0001) of mica muscovite, on their thickness d=(0.1–1) microns were studied. The effective mean free path of charge carriers was detected and the dominant scattering mechanism was determined. Within the two-layer Petritz model an estimation the thermoelectric parameters extent of surface layers was carried out. It has been found that the condensate has stable n-type conductivity and there is diffuse scattering on the surface, which leads to a significant decrease in relation to the films volume for mobility, conductivity, and increasing Seebeck efficient. |
