Graphene specific heat
WebOct 3, 2011 · The study of specific heat is limited to blanket graphene [19]. It is challenging to estimate the specific heat behavior in natural GNR nanodevices because of free boundary conditions (FBCs), especially with complexation due to chemical groups or dangling bonds at GNR edges. WebDue to the transitory kinetic energy of the molecules, graphene has two degrees of freedom and two vibrational degrees of freedom because it is two-dimensional. As a result, in equation, the thermal energy is provided by Δ E th = 6 2 n R Δ T = 3 n R Δ T. Step: 3 Molar Specific heat of Graphene: The Specific heat is mentioned by Δ E th = n C Δ T.
