For many potential applications in nanotechnology, graphene’s thermal and mechanical endurance is essential. Applying stresses more than 15% can alter the band structure of the material. We ascertain the temperature dependence of the volume thermal expansion, bulk modulus, and thermal expansion coefficient of graphene using the equation of state (EOS) based on thermodynamic variables. A straightforward theoretical technique is used to determine the thermal expansion and thermal expansion coefficient of graphene. Potential is unaffected by the model utilised in this study, which only includes two input parameters.
