摘要: The energy spectra of an electron in an asymmetric quantum well within an in-plane magnetic field and an electric field perpendicular to the barrier interfaces are exactly derived and the numerical results are calculated by iteration. The ground and excited states are calculated for various asymmetric potential barriers, well widths and electric fields. Major different characteristics of energy spectra between wide and narrow wells are discussed. The behaviors of a bulk Landau level in the well region of a larger well width and the elevation of the ground state in a smaller well width are explained. The density distribution of electrons in a large well region is strongly affected by the barrier ratio and the electric field in the growth direction.
