Abstract
We consider a finite superlattice consisting of unit cells with quantum wells filled with different types of carriers. The density-density correlation function is calculated with use of the random-phase approximation. The theory of resonant Raman scattering and inelastic electron scattering is formulated. The general theory is applied to a type-II superlattice. Raman and electron-energy-loss spectra due to bulk and surface plasmons are predicted for various system sizes.
