Electron energy spectrum and oscillator strengths of quantum transitions in double quantum ring nanostructure driven by electric field
The effect of homogeneous electric field on the energy spectrum, wave functions of electron and oscillator 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 calcu...

Показано, що електричне поле суттєво впливає на локалiзацiю електрона у системi нанокiлець.

| description |
The effect of homogeneous electric field on the energy spectrum, wave functions of electron and oscillator
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. |
