A method for calculating the Landau levels of symmetric p ‐type inversion layers is presented. Using the envelope function approach in the Hartree approximation the magnetic field is incorporated into the Hamiltonian. In order to characterize the energy levels and to obtain a detailed understanding of the unusual Landau scheme, an analysis of the wave functions is made. Special effects are discussed for the inversion layers adjacent to the grain boundary of a Ge‐bicrystal, with two occupied subbands. The simulation of Shubnikov‐de Haas data by a density of states analysis shows that the different oscillatory periods are not directly related to the subband occupations.
