Frustrated phase separation in two-dimensional charged systems

Abstract

We study phase separation frustrated by the long-range Coulomb interaction in two dimensional electronic systems with emphasys in the case of a metallic and an insulating phase. We find that two-dimensional systems are more prone to mesoscopic frustrated phase separation than the three dimensional ones.
