ABSTRACT

Using Molecular Dynamics simulation we have investigated the melting properties of a 2-dimensional system of ions interacting through a screened coulomb potential in the presence of a substrate. We focus on the role of substrate potential in the melting transition. The physical system we study is the stage 2 graphite intercalation compound RbC24 and a related system RbC24.57 whose intercalant density differs from the former by a small amount. Our results reveal the nature of melting processes characteristic of periodic domain walls.
