Dependence of the Galvanomagnetic Properties of Bismuth-Antimony Thin Films on Their Composition and Crystal Structure

Abstract

The influence of composition and structure on galvanomagnetic and thermoelectric properties of Bi-Sb thin films is studied. The comparison of properties of block textured and monocrystalline films, made by the method of floating-zone refining under covet, is carried out. The influence of grain-boarder scattering of charge carriers on galvanomagntic properties is pointed out. Mechanical deformation, which occurs in film-substrate system, essentially effects galvanomagntic properties. According to the experimental data, charge carrier mobilities were counted for BiSb films.
