Molecular dynamic analysis of pristine single layered graphene for mass sensor

Abstract

The impact of mass on the resonance frequency of single-layered pristine graphene is examined in this research paper. Graphene is viewed as a fascinating material in modern era. In mass sensing, graphene has a significant potential. The authors of this work explored the appliance of single layer graphene (SLG) as a sensing device. The dynamic analysis of SLG is carried out with various boundary conditions. The atomistic finite element technique is used to simulate SLG. SLG sheets have been modelled. The mechanical properties of covalently bound carbon atoms in a hexagonal structure are also used to compute the physical properties of beam elements. At nodes that correspond with carbon atoms, each beam element's mass is represented as a point mass. Simulations were done to see how SLG responded to different conditions of boundary and when used as a mass sensor. Changing the length and applied mass of SLGs reveals the frequency variation. The obtained results show that the length of the sheet and varied mass values have a substantial influence on the dynamic properties. The results reveal that when mass increase, the sensitivity of the SLGS-based mass sensor increases.
