Abstract: a b s t r a c tWe have described the calculation of hydrogenic impurity binding energies in cylindrical GaAs-Ga 1−x Al x As quantum well wires (QWWs) with lateral parabolic confinement in the presence of an axial magnetic field. The numerical calculations of this system have been performed with the use of a variational procedure in the effective mass approximation. We observed sharp changes in binding energy for critical spatial confinement radius and B magnetic field values.
