✦ Synopsis

We have studied the charge-density oscillations (plasmons) of a two-dimensional electron gas within the framework of finite temperature and frequency independent (static) version of Singwi, Tosi, Land and Sj ΓΆlander approximation. We have shown that even at high densities the finite temperature and layer thickness have non-negligible impact on plasma dispersion of the two-dimensional electron system.

Upon decreasing the density, the 2D electron system exhibits a transition from the metallic state, characterized by the Quantum Hall effect, to the collective insulating state (electron solid), interrupted by the Quantum Hall effect at integer fdling factors v = 1, 2, and 6. The electron solid shows
