The effect of an intense laser field on the binding energy of hydrogenic impurity states with an impurity atom located at the center of a spherical quantum dot confined by an infinite barrier potential are studied as a function of the dot radius and of the intensity and frequency of the laser field.
Using the effective mass and parabolic band approximations and a variational procedure we have calculated the combined effects of intense laser radiation, hydrostatic pressure, and applied electric field on shallow-donor impurity confined in cylindrical-shaped single and double GaAs-Ga 1-x Al x As Q
In this study, the intense laser-field dependence of intersubband absorption coefficient for 1-2 transition in GaAs/Ga 1Àx Al x As DGQW under the electric field is investigated. The obtained results show that by changing the laser intensity together with the electric field and the well parameters (w
