Popis: We report studies of the surface plasmon modes of a layer of electron gas that is embedded in a wider, effective positive background, provided by a parabolic Al x Ga 1-x As well. Although conditions in the interior of the electron gas are nearly identical to those in a neutral hellium slab, the more abrupt electronic surfaces in the parabolic well produce a qualitatively different surface plasmon spectrum
