St. Perez-merchancano et Ge. Marques, Photoluminescence in cylindrical quantum well wires in the presence of shallow impurities and magnetic field, PHYS ST S-B, 212(2), 1999, pp. 375-381
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.
