摘要：

The authors discuss the use of X-ray and Raman scattering to probe structural disorder in aperiodic GaAs-AlxGa1-xAs superlattices, including random and quasiperiodic examples. Evidence is found for the presence of monolayer-thick steps at the interfaces. The X-ray data appear more sensitive to this type of disorder than the acoustic phonon spectra obtained by Raman scattering.
