A first-principles calculation of the high-frequency conductivity for a two-dimensional, two-component electron gas is presented. Both frequency and temperature dependence are considered. The influence of electron-electron collisions on the two-dimensional plasmon is discussed in relation to possible experiments in MOS structures.
