Query: Frustrated phase separation in two-dimensional charged systems   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.
