A Review of Graphene on NEMS.
Abstract
BACKGROUND: Graphene is a new type of two-dimensional crystal material, and its single atomic layer structure shows many excellent physical and chemical properties such as large specific surface area, good electrical conductivity and high Young's modulus. However, few relevant patents to the topic have been reviewed and cited. This paper mainly deals with the methods of the preparations of graphene and graphene applications in NEMS sensors, NEMS devices, optics, energy storage, and biomedical fields.
METHODS: At present, compared with the less effective experimental research method, the numerical simulation method has become an effective research approach. Molecular dynamics is widely used in the numerical simulation calculation. Molecular dynamics can simulate the change process of graphene in real environments. Molecular dynamics reveals the microscopic deformation under the action of external load.
RESULTS: The analysis process of two structures is mainly through the external stretched or compressed force exerted on the graphene. The Young's modulus of the simulated graphene is about 0.86TPa. The simulated tensile strength is about 121GPa.The resonance frequency of graphene resonators can be changed by the tension of both ends of the beam. As the initial strain increases, the resonance frequencies also increase. For very small initial axial -strain, the tunable range reached above several hundred gigahertz. As the initial axial -strain of graphene increased, the tunable…
How strong is the evidence?
Evidence Hub reads this as a review, done in computer models (in silico), not in people. Its evidence level is 5 of 5 (Very low · case / narrative / animal / in vitro / in silico). Case reports, narrative reviews, and animal, cell or computer-model studies give the weakest evidence for human health.
