Optical properties of magnetoplasmons in multiple quantum wells

摘要

Using the random-phase approximation, the density-density correlation function including intra- and inter-Landau level transitions in multiple quantum wells is obtained under magnetic fields parallel to interfaces, on the basis of a simple model of parabolic confining potentials. The Raman intensities for the bulk and surface magnetoplasmons are investigated as a function of the number of quantum wells, the ratio of the confining potential parameter to cyclotron resonance frequency, and the momentum wave vector.
