Application of Statistical Mechanics for Thermodynamics Properties of Graphene

In this paper, we have been used energy spectrum of ideal single layer graphene to investigate thermodynamic properties of this material. We have used Shannon and Tsallis entropies for investigating the entropy, internal energy and specific heat of this system. We plot these properties versus temperature. The obtained results show that the entropy and internal energy increase with enhancing the temperature and then these reach to a constant values. Also, the specific heat increases until it reaches a maximum and then reduces with increasing the temperature.
