Paper Abstract

The binding energy of a shallow donor in a parabolic quantum well subjected to a longitudinal electric field and an intense laser field radiation is calculated with use of a variational method. It is shown that the electric field effect on the "dressed" impurity states depends on the position of the donor within a quantum well of finite depth. The laser field can essentially change single-electron spectra in the structure. This may be useful for understanding physical phenomena and designing optoelectronic devices.
