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.

带有对称对称尺寸的纳米结构中载体的非单调分散。

摘要

考虑了一维非对称半导体纳米系统中的能谱特征和载流子运动。量子阱中势能轮廓上有一个额外的下降的不对称结构，使人们可以改变尺寸量化水平的位置。外部磁场的附加影响导致载流子的非单调弥散和横向局部漂移。这种对基本对称性的违反将导致电子跃迁的性质发生相应的变化。根据外部磁场的强度，对具有量子轮廓不对称性的纳米结构电子系统的动力学特性进行了分析。
