RESONANT RAMAN-SCATTERING FROM CONFINED PHONONS AND INTERFACE PHONONS IN A GAAS/GAALAS SUPERLATTICE
We have studied the optic phonons of a GaAs/GaAlAs superlattice (d//G//a//A//s equals 55 Angstrom, d//G//a//A//l//A//s equals 175 Angstrom using resonance Raman spectroscopy. Resonance was obtained with the n equals 2 electron - heavy - hole excition of the GaAs quantum well, and with a bound excito...
