中文摘要: 石墨烯因其独特的结构和特性，具有广泛的应用前景。本文采用分子动力学的方法模拟石墨烯被硅探针压变形后弯曲振动的动力学过程，探讨了石墨烯纳米带的尺寸和温度对石墨烯纳米带谐振特性的影响。模拟结果表明，石墨烯纳米带的谐振频率随着石墨烯纳米带的长度、宽度、层数（厚度）以及温度变化。其中宽度、厚度和温度对石墨烯纳米带谐振频率的影响较小，影响石墨烯纳米带谐振频率的主要因素是长度。

Abstract:Graphene has unique structure and characteristics, which would be used in many fields. In this paper, the resonant frequency of graphene nanoribbons is studied by the molecular dynamics simulation method, which performed by modulate the dynamic process of bending vibration after deformation by silicon probe. The effects of graphene nanoribbon size and temperature on the resonant frequency of graphene nanoribbons were investigated. The simulation results show that the resonant frequency of graphene nanoribbons varies with the length, width, layers (thickness) and temperature of graphene nanoribbons. The effects of width, layers (thickness) and temperature on the resonance frequency of graphene nanoribbons are small, and the length of graphene nanoribbons is the main factor，which affect the resonance frequency of graphene nanoribbons.
