Light scattering from a layered electron gas

Journal Article


Abstract


  • The Raman scattering cross section from a two-component layered electron gas (such as in InAs-GaSb, GaAs-AlxGa1-xAs superlattices, etc.) has been calculated. It is found that for a separation between the two components larger than a critical value, the scattered spectra have two resonant peaks in the high-frequency regime. For small separation and small mass ratio, there is a resonant peak due to an ion acoustic mode in the low-frequency regime and to a plasma mode in the high-frequency regime. © 1986 The American Physical Society.
