| Abstract
|
| The excellent mechanical and electrical properties of graphene make it an ideal material for nanoelectromechanical resonators. The effects of doping elements and doping concentrations on the vibration characteristics of monolayer graphene nanoribbons were studied by molecular dynamics simulation. The results show that the vibration frequency of single-layer graphene nanoribbon decreases with the increase of nanoribbon length. Boron (B) doping, Boron-Boron (B-B) doping, Beryllium (Be) doping and Beryllium-Beryllium (Be-Be) doping all lead to the decrease in vibration frequency of single layer graphene nanoribbons. In addition, with the increase of the Boron (B)/Beryllium (Be) doping concentration, the vibration frequency of the single-layer graphene nanoribbon gradually decreases. With the increase of doping concentration, the difference of vibration frequency between Boron (B) doped graphene nanoribbons and Beryllium (Be) doped graphene nanoribbons gradually increases. It has a certain theoretical significance for the design of graphene nanomechanical resonators, oscillators and other nanodevices. |
