Abstract
The charged layers on a liquid-He surface and the inversion layers on a semiconductor-insulator interface exhibit properties which are treated by assuming that they are a two-dimensional electron gas. We have calculated the dispersion relation for the frequency of plasma oscillations taking into account the finite width and correlation effects. We find important deviations from the corresponding result for the two-dimensional electron gas.Keywords
