Non-Monotone Dispersion of Carriers in Size-Quantized Nanostructures with Violated Symmetries

Abstract

The features of the energy spectrum and the movement of carriers in one-dimensional asymmetric semiconductor nanosystems are considered. Asymmetric structures with an additional dip in the potential profile in the quantum wells allow one to vary the positions of the dimensionally quantized levels. An additional influence of the external magnetic field leads to non-monotonic dispersion and lateral local drift of carriers. Such violations of fundamental symmetry will entail corresponding changes in the nature of electronic transitions. The analysis of the dynamic properties of the electronic system of the nanostructure with the asymmetry of the quantum profile was carried out, depending on the intensity of the external magnetic field.
