strengths of intra-band quantum transitions in a double cylindrical quantum ring (GaAs/AlxGa1−xAs) is studied
within the approximations of effective mass and rectangular potentials. The calculations are performed using
the method of expansion of quasiparticle wave function over a complete set of cylindrical wave functions obtained as exact solutions of Schrödinger equation for an electron in a nanostructure without electric field. It is
shown that the electric field essentially affects the electron localization in the rings of a nanostructure. Herein,
the electron energies and oscillator strengths of intra-band quantum transitions non-monotonously depend on
the intensity of electric field. |
