PACS numbers: 63.22.Rc, 65.40.Ba, 65.40.De, 65.80.Ck, 81.05.ue

Graphene is the emerging area of nanomaterials due to their prospect for coming generation electronic devices. Various studies of graphene have been carried out to investigate the phonon properties, elastic properties. However, the physicothermal properties such as heat capacity and Gruneisen parameter have been neglected. The Gruneisen parameter is the main physical parameter in thermal expansion mechanisms. These parameters are generally positive for some modes, but they are found to be negative for q values in high-symmetry directions. They are found negative for acoustic mode in case of graphene. The Debye model for the specific heat at low temperatures is also taken into account for acoustic branches. The heat capacity of the graphene is also computed. Physicothermal properties investigated by PYTHON program is agreed very close with the result of other researchers.

KEY WORDS: Hamiltonian mechanics, harmonic oscillators, heat capacity, thermal properties of graphene
