摘要：

A numerical investigation of the single-particle energy spectrum of two-dimensional electrons subject to a periodic potential of square symmetry and a perpendicular magnetic field is presented. Our approach allows variation of both the steepness and the strength of the modulation potential. It is shown that the inclusion of coupling between different Landau levels has a strong impact on the appearance of the subband structure. The possibility of finding experimental indications of the spectrum is discussed in the Light of the present calculations.
