Influence of temperature on the modal behavior of monolayer graphene sheets

Abstract: In this work, the vibrational behavior of rectangular monolayer graphene sheets is predicted at different environmental temperatures. Graphene sheets are modeled according to their molecular structure via finite element analysis. Using molecular mechanics theory, the potential energy of graphene is expressed as temperature-dependent. The graphene interatomic interactions are simulated by spring elements, and the nodes of the model represent the carbon atoms. The carbon atom mass is considered in the assembly a… Show more

“…1421 nm is the carbon-carbon bond distance at room temperature, α is coefficient of thermal expansion of carbon-carbon bond (Chen et al, 2009) and ΔΤ is the 656 IJSI 11,5 temperature variation. In a previous work of Tsiamaki et al (2018), the specific methodology is thoroughly presented and has been validated concerning the thermodynamic response of rectangular graphene sheets. Considering that the bond distance represents the average equilibrium length at a particular temperature, we find the mechanical properties of graphene as a function of temperature.…”
