The electron sub-band energy of a cubic GaAs/AlAs quantum dot under an applied spatial electric field is theoretically investigated within a variational scheme. In this case, we show that the electron sub-band energy E decreases with spatial electric field strength F and increases or decreases depen
The binding energy of a donor impurity in a spherical GaAsยฑ(Ga,Al)As quantum dot with parabolic confinement is calculated as a function of the radius of the quantum dot and as a function of the intensity of an applied electric field. Calculations are performed within the effective-mass approximation
