Cyclotron-Intersubband Coupling in Periodically Modulated Quasi-Two-Dimensional Electron Gas
Languages of publication
The problem of the coupling between the Landau levels originating from the ground and first excited subband in laterally modulated quasi-two-dimensional systems in the presence of the tilted magnetic field is discussed in the framework of the one-electron perturbation theory. It was found that the tilting of the superlattice potential leads to the strong dependence of this coupling on the orientation of the magnetic field with respect to the lateral confinement direction.
