Optically detected electrophonon resonance effects in quantum wells

Optical detected electrophonon resonance (ODEPR) effects in quantum wells of n-GaAs materials are investigated for square potential and parabolic potential, respectively. We also obtain the ODETR conditions is functions or confinement frequency in parabolic potential and well-width in Square potential for the various photon frequencies, respectively. In particular, anomalous behaviors of the ODEPR lineshape such as the splitting of ODEPR peaks for incident photon frequency are discussed. Furthermore. we obtain the selection rules for transition in quantum Wells Of two different potentials, respectively. (c) 2005 Elsevier B.V. All rights reserved.
