We investigate the influence of phonon confinement on the optically detected magneto-
phonon resonance (ODMPR) effect and ODMPR line-width in quantum wells. The ODMPR
conditions as functions of the well's width and the photon energy are also obtained. The
shifts of ODMPR peaks caused by the confined phonon are discussed. The numerical result
for the GaAs/AlAs quantum well shows that in the two cases of confined and bulk phonons,
the line-width (LW) decreases with increasing well's width and increases with increasing …

We investigate the influence of phonon confinement described by the slab mode model on
the optically detected magneto-phonon resonance (ODMPR) effect and ODMPR line-width
in parabolic quantum wells by using the operator projection. The ODMPR conditions as
functions of the well's parameters and the photon energy are also obtained. The shifts of
ODMPR peaks caused by the confined phonon are discussed. The numerical result for a
specific quantum well shows that in the two cases of confined and bulk phonons, the line …
