We report a calculation of the absorption coefficient of donor impurities located at the center of a quasi-1D GaAs quantum well wire with finite confinement potential as a function of photon energies for different wire widths. The theory has been formulated by using suitable variational wave functio

The influence of interdiffusion on eigenstates in an interdiffusion-induced GaAs/ AIxGal\_xAs single-quantum-well structure is analysed numerically by the finite element method. In this approach, the confinement potential profile of the interdiffused quantum well structure is nonlinear and is modell
## Abstract The effects of intense laser radiation on the exciton states in GaAsβGa~1β__x__~Al~__x__~As quantum wells are studied with the inclusion of applied dc electric fields oriented along the growth direction of the system. The calculations are made within the effective mass and parabolic ban
