Abstract
We present a systematic study of properties of photoluminescence in a cylin drical quantum well wire doped with shallow acceptor impurities and in the presence of a uniform magnetic field applied parallel to the wire axis. We calculate the binding energy of all impurities localized on the axis of the wire for different magnetic fields and this structure preserves the axial symmetry both with and without the field. For room temperature properties a t low magnetic field regime, we calculate the carrier densities and several radiative recombination times, under steady-state excitation condition, as a function of the cw-laser intensity and for different acceptor densities.
