Phys. Rev. B 36, 5949–5952 (1987)Elementary electronic excitations in a quasi-two-dimensional electron gasReceived 4 June 1987; published in the issue dated 15 October 1987 The complete elementary excitation spectrum for a quasi-two-dimensional electron gas is calculated within the random-phase approximation for both single and multilayer systems. Specific predictions are made for the direct observation via inelastic light scattering of a number of new modes and mode-coupling effects. © 1987 The American Physical Society URL:
