Abstract

A systematic study of the binding and transition energies associated with the ground and some excited states of a hydrogenic on–center donor in a cylindrical GaAs quantum-well wire, in the simultaneous presence of intense high– frequency laser and static magnetic fields is performed. We use a variational procedure within the effective-mass approximation. The results show that the electronic and optical properties strongly depend not only on the “laser-dressed” Coulomb potential, but also on the quantum confinement and the applied magnetic field..
