STABILITY OF GRAPHENE SURFACE AN APPLICATION OF CHIRAL MODEL

Abstract

A suspended sheet of pure graphene a layer of carbon atoms bonded together in a honeycomb
lattice is the most two-dimensional system imaginable. Graphene sheet have for long been known
to exist in disguised from graphite (stacked graphene layers) it was generally believed that an
extended graphene sheet would not be stable against the effect of thermal and other fluctuations.
Furthermore, it was believed that even if they were stable, it would be impossible to isolate them
so that their properties could be studied systematically. Based on this the chiral model was
suggested, the ideal graphene plane were determined by the kink-like solution. The corrugation of
the graphene surface was described in the form of ripple and rings. Thus, our graphene plane
reviles the tendency of bending.
