The carrier mobilities and concentrations of polycrystalline films of Bi 0.87 Sb 0.13 with thicknesses between 30 and 330 nm are presented and discussed in the temperature range between 80 and 360 K. They are calculated from the electrical conductivity as well as the low‐field Hall and magnetoresistance coefficients in a magnetic field directed orthogonally to the film plane. An anisotropic two‐carrier model is taken as a basis for the calculation.
