摘要：

Electronic states and interband transitions in the cylindrical quantum layer Ga1-x1Alx1As/GaAs/Ga1-x2Alx2 As are studied. As a confinement potential the radial analogue of Smorodinsky-Winternitz potential is considered. The quantum transitions are studied in dipole approximation at the presence of the magnetic field directed along layer axis. The selection rules and threshold frequencies of absorption for transitions between heavy holes' band and conduction band, as well as light holes' band and conduction band are obtained. It is shown that these frequencies lie in visible red and near infra-red spectrum. In the frame of perturbation theory the influence of the weak electric field on the character of interband transitions is discussed. In particular, it is found that selection rules for interband transitions change depending on electric field orientation.
