An extrinsic semiconductor with periodic impurity distribution is studied. The distribution function in such a semiconductor applied to a mutually perpendicular heating electric field and a classically strong magnetic field is determined. The spectrum of electron gas eigenoscillations is calculated. The frequencies of eigenoscillations are proved to be considerably sensitive to the electric field strength. The spatial periodicity of the semiconductor changes the number of vibrational modes. Similarly to other works, semiconductor inhomogeneity results in resonance‐type dependencies for some modes. The magnetic field is also found to be the factor changing significantly the spectrum of eigenoscillations.
