ABSTRACT

The temperature dependence (in the 78 K – 300 K range) of the following components of the tensor of electric resistance in low magnetic field – two components of specific resistance (ρ11 and ρ33), two components of Hall effect (R231 and R123) and, five components of magnetoresistance (ρ11,11, ρ11,22, ρ11,33, ρ33,11, ρ33,33) – for the alloys of Bi0.97Sb0.03 and Bi0.94Sb0.06 were measured. Due to the calculations the following kinetic parameters were determined: carrier densities of electrons N and holes P; their mobilities μ1, μ2, μ3 and ν1, ν3, correspondingly; and the tilt angle of electronic isoenergetic ellipsoids to the bisectrix axis (φe). Calculations were carried out for two- (L electrons and T holes) and three-band (L electrons, T and L holes) models

Keywords: semimetals, galvanomagnetic properties, kinetic coefficients of Bi-Sb alloys
