Abstract
We study inelastic light scattering from a two-dimensional electron gas subject to a weak in-plane one-dimensional periodic potential modulation and a perpendicular magnetic field. Electronic Raman scattering is considered for (i) inter-Landau-level transitions, which result in a Raman shift of \ensuremath{\sim}2${\mathrm{\ensuremath{\omega}}}_{\mathit{c}}$, and (ii) transitions involving collective excitations at the hybridized magnetoplasmon frequency and a modulation-indued, low-frequency intra-Landau-level plasmon. Raman cross sections and their dependencies on the magnetic field strength and the modulation potential/density are examined.
