Frustrated phase separation in two-dimensional charged systems

TL;DR

This paper investigates how long-range Coulomb interactions cause frustrated phase separation in two-dimensional electronic systems, especially between metallic and insulating phases, highlighting their increased tendency for mesoscopic separation compared to three dimensions.

Contribution

It reveals that two-dimensional systems are more susceptible to mesoscopic frustrated phase separation due to Coulomb interactions than three-dimensional systems.

Findings

Two-dimensional systems show higher propensity for mesoscopic phase separation.

Frustrated phase separation is influenced by long-range Coulomb interactions.

Comparison indicates dimensionality affects phase separation behavior.

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.
