| description |
The effect of a constant electric field and donor impurity on the energies and oscillator strengths of electron
intraband quantum transitions in double-well spherical quantum dot GaAs/AlxGa1−xAs/GaAs is researched.
The problem is solved in the framework of the effective mass approximation and rectangular potential wells and
barriers model using the method of wave function expansion over a complete set of electron wave functions in
nanostructure without electric field. It is shown that under the effect of electric field, the electron in the ground
state tunnels from the inner potential well into the outer one. It also influences on the oscillator strengths of
intraband quantum transition. The binding energy of an electron with ion impurity is obtained as a function of
electric field intensity at a different location of impurity.
