The single-walled carbon nanotube (CNT) is a quasi-1D material with ultra high thermal conductivity. It is known that the heat conduction is closely related with the energy diffusion and the information of heat conduction can be obtained by examining the energy diffusion behavior. The correlated energy distribution C E ( i , t ) calculated in diffusion process gives the whole spatial distribution of energy spreading at every correlation time which is much better than the traditional heat conduction method where only a number of thermal conductivity is provided. In previous study the anomalous super-diffusion of energy has been reported for CNT via a non-equilibrium diffusion method. Here we apply the more sophisticate equilibrium diffusion method to investigate the energy diffusion behavior in CNT with much longer length up to ##IMG## [http://ej.iop.org/images/0022-3727/53/14/145302/dab69adieqn001.gif] m with much highe...

一维单壁碳纳米管的能量和动量扩散行为

单壁碳纳米管（CNT）是一种具有超高导热率的准1D材料。已知热传导与能量扩散密切相关，并且可以通过检查能量扩散行为来获得热传导信息。在扩散过程中计算出的相关能量分布CE（i，t）给出了每个相关时间的能量散布的整个空间分布，这比仅提供大量导热系数的传统热传导方法要好得多。在先前的研究中，已经报道了通过非平衡扩散方法对碳纳米管进行异常的能量超扩散。在这里，我们使用更复杂的平衡扩散方法来研究碳纳米管中的能量扩散行为，碳纳米管的长度更长，直至## IMG ## [http：// ej。
