  Silicene is the counterpart of graphene and its potential applications as a
part of the current electronics, based in silicon, make it a very important
system to study. We perform molecular dynamics simulations and analyze the
structure of a two dimensional array of Si atoms by means of the radial
distribution function, at different temperatures and densities. As a first
approach, the 2D Lennard-Jones potential is used and two sets of parameters are
tested. We find that the radial distribution function does not change with the
parameters and resembles the corresponding to the (111) surface of the FCC
structure. The liquid phase appears at very high temperatures, suggesting a
very stable system in the solid phase.
