典型纳尺度结构的热振动

刘汝盟,王立峰

 

摘要:热振动是一定温度下纳尺度结构的固有运动,对其动力学行为有着重要的影响。当空间进入纳米尺度,结构呈现离散性,量子效应、边界效应、范德华力等变得不可忽略,纳尺度结构在热噪声随机激励下的动力学行为表现出众多异乎寻常的特性。以碳纳米管和石墨烯为代表的纳尺度碳材料具有优良的力学、电学和化学性质。在此介绍多种针对纳尺度结构热振动问题的研究方法、及碳纳米管和石墨烯的低温热振动、碳纳米管的非线性热振动研究进展。

Thermal vibration of typical nano-structure

Rumeng Liu, Lifeng Wang

 

AbstractThe thermal vibration is the inherent vibration of nanostructures, which plays an important role in the dynamics of nanostructures. The quantum effects, the boundary effects and the van der Waals interaction have a significant influence on the thermal vibration of nanostructures. The carbon nanotubes and the graphene were extensively studied for their novel electronic properties and superior mechanical strength. This paper reviews some research methods for the thermal vibration of nanostructures, the thermal vibration of the carbon nanotube and the graphene in low temperatures and the nonlinear thermal vibration of the carbon nanotube.
