Abstract | We report the observation of AlGaAs optical phonon replicas in the photoluminescence spectra from GaAs layer of an Al0.3Ga0.7As/GaAs heterostructure at low temperature. The AlAs-like transverse and longitudinal optical modes of Al0.3Ga0.7As alloy are observed by using excitation light with 488 nm wavelength. Also, the replicas involving one and two GaAs-like longitudinal optical phonons are observed when the excitation light used is He-Ne laser with 632.8 nm wavelength. The phonon energies determined from our measurement are in agreement within 10% with those expected. Copyright © 1996 Published by Elsevier Science Ltd. |
