研究了C(60)包覆对单壁碳纳米管(SWCNTs)径向呼吸模式(RBM)频率的影响。观察到的频移表现出依赖于C(60)和SWCNTs之间的间距的特征行为。目前的发现清楚地表明了SWCNT-C(60)相互作用的van der Waals性质，以及C(60)和SWCNTs电子态之间杂交的重要性。
The effects of C(60) encapsulation on the radial breathing mode (RBM) frequencies of single-wall carbon nanotubes (SWCNTs) are investigated over a wide range of diameters (d(t) approximately 1.25-1.5 nm). The observed frequency shifts show a characteristic behavior depending on the inter-spacing between C(60) and SWCNTs. The present findings clearly indicate the van der Waals nature of the SWCNT-C(60) interaction and an importance of hybridization between the electronic states of C(60) and SWCNTs.
