我们在近红外和可见光频率范围内对填充C60分子的单壁碳纳米管（SWCNTs）进行了压力相关的透射测量，在此范围内，碳纳米管的Van Hove奇点之间的光学跃迁被激发。压力诱导的光学跃迁表现出与碳纳米管变形相关的异常。将结果与空SWCNTs的结果进行比较。此外，还讨论了测量中使用的传压介质的重要性。
We carried out pressure‐dependent transmission measurements on single‐walled carbon nanotubes (SWCNTs) filled with C60 molecules, so‐called C60 peapods, in the near‐infrared and visible frequency range, where the optical transitions between the Van Hove singularities of the carbon nanotubes are excited. The pressure‐induced shifts of the optical transitions exhibit an anomaly associated with the deformation of the carbon nanotubes. The results are compared with those for empty SWCNTs. Furthermore, the importance of the pressure transmitting medium used in the measurements is discussed.
