Abstract
On the basis of the quasistationary state approximation, the asymptotic transfer method (ATM) was extended to calculate the energy spectra, envelope functions of carriers and dispersion relations of Ga1−xAlxAs multiple sawtooth quantum wells (MSQW) in the presence of an electric field applied along the growth direction and a magnetic field parallel to the MSQW interfaces. It turned out that the energy spectra revealed the Landau-like behavior of carriers under a magnetic field. The envelope functions of carriers displayed obvious fluctuation and the dispersion relations showed a non-parabolic shape.
