Two-Body Correlations and the Underlying Phase Transitions in Bilayers

Abstract

The pair correlation functions for a bilayer system of classical electrons has been calculated through a two-component HNC formalism. The results show changes in the structure of the correlation functions as the interlayer distance is increased from zero to about twice the Wigner-Seitz radius. These changes are indicative of structural phase transitions which are expected to take place in the crystallized phase and whose short range orders the liquid phases emulate.
