We performed the precision measurements of the near-normal far-infrared reflection and transmission spectra of the MBE-grown (GaAs) n /(AlAs) n (n = 1, 2, 4) superlattices. The results obtained show a noticeable (almost twofold) increase in the AlAs-phonon damping when n is decreased from 4 to 1. We
We present symmetry analysis, Raman and Brillouin scattering selection rules and Raman spectra of \((\mathrm{GaAs})_{m} /(\mathrm{AlAs})_{n}\) superlattices grown on \(\mathrm{GaAs}\) substrates of (211) orientation. Using lattice dynamical calculations based on the shell model, an assignment of the
