Cyclotron resonance (CR) measurements have been carried out to evaluate the effective masses of electrons at the AlAs X point of the Brillouin zone in short period (GaAs),/(A1As). superlattices (SLs) with n = 8-14. The longitudinal effective mass was deduced to be m 1 = 1.04m 0 by analyzing a deviat
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
