Low-Dimensional Systems


The possibility of plasma oscillations occurring in a two-dimensional electron gas with a superstructure was studied taking into account the Umklapp processes. In the case of high temperatures (
where Δ is the width of the conduction miniband and T is temperature expressed in energy units), the dispersion relation ω(k) was obtained. It is shown that, for small values of
, the plasmon spectrum features the characteristic dispersion ω2k, which corresponds to a two-dimensional electron gas without a superstructure. For arbitrary values of k, the spectrum is periodic with a period of 2π/d. Numerical estimation of the characteristic frequency of the plasma oscillations for the two-dimensional superstructures currently under experimental investigation yields 1013 s−1.
