✦ Synopsis
A variational formalism for calculating the binding and the transition energies between 1s-and 2 p ± -like states of a shallow donor in cylindrical pills of GaAs low-dimensional systems, under the action of the electric and magnetic fields applied in the axial direction, is presented. Results were obtained for several values of the magnetic field as a function of the system geometry and the applied electric field. Within the two-dimensional limits, the theoretical results for the 1s-2 p + transition energies are in good agreement with infraredmagnetospectroscopy measurements on donor doped quantum-wells.
