Binding energy and self-polarization as function of energy density in GaAs/AlAs quantum well wires

In this work, we have investigated the effect of both external electric and magnetic fields on the ground-state binding energy and the self-polarization of hydrogenic impurity in square and cylindrical GaAs/AlAs quantum well wires as function of energy density and impurity position. The binding energies and self-polarizations were obtained using the effective-mass approximation within a variational scheme.
