Description

The features of the energy spectrum and carrier motion in one-dimensional asymmetric semiconductor nanosystems are considered. Asymmetric structures with an additional dip in the potential profile in quantum wells make it possible to vary the positions of size-quantized levels. And the additional influence of an external magnetic field leads to non-monotonic dispersion and a transverse local carrier drift. Such violations of fundamental symmetries will entail corresponding changes in the nature of electronic transitions. The dynamic properties of the electronic system of the nanostructure with the asymmetry of the quantum profile are analyzed, depending on the strength of the external magnetic field
