Site‐Dependent Migration Behavior of Individual Cesium Ions Inside and Outside C60 Fullerene Nanopeapods
Source abstract
Abstract
Cesium-doped fullerene nanopeapods are characterized using high-resolution transmission electron microscopy. Individual cesium ions (Cs+) inside and outside the nanopeapods (see image) are found to exhibit different migration behavior depending on their sites.

14. This nanopeapod represents a particular case in which Cs+ions are allowed to take only limited positions due to elastic deformation of the outer SWNT. See also Figure 3.

17. The C60intermolecular distance in the nanopeapod (c) without Cs+ions inside is 0.95 ± 0.03 nm which agrees with the values in Ref. [11].

20. The position of this nanopeapod did not shift and the contrast profile of the SWNT wall was not significantly changed from frame to frame in Figure 3. These results indicate that fluctuation of the apparent diameter is not caused by either rotation of this nanopeapod on the TEM grid or mechanical drift of the specimen.
21. Some of the defects are considered to exist originally in as‐grown nanotubes and others are introduced into the nanotubes during the cap‐opening process for C60incorporation or during TEM observation.
