| Popis: | Now a day’s graphene is of keen interest for its application in carbon nanotube Field Effect Transistors, Graphene Transistors etc. Graphene is a single layer of graphite which is 2D in structure. In this paper, we are focusing on the thermal property of graphene. For 3D crystalline graphite and 2D graphene layers, the dominant contribution for the heat capacity comes from the phonons. This is because the electronic contribution to the heat capacity is very small and hence can be essentially neglected, even at low temperatures. In this paper we have calculated the lattice specific heat of graphene in a simpler method and studied its variation with respect to the number of nearest neighbors considered for the calculation as well as temperature. |
