Sažetak
An attempt is made to investigate theoretically the effective mass of the holes at the Fermi level in bismuth at low temperatures in the presence of a DC quantizing magnetic field along the trigonal axis by using the Abrikosov dispersion relation allowing various types of anisotropies in the energy spectrum. It is found that the dependence of the same mass on the Fermi energy and the magnetic quantum number is due solely to the effect of band non-parabolicity and is a characteristic feature of Abrikosov model. In addition, the corresponding well-known results of anisotropic parabolic energy bands are also obtained from the expressions derived.
