Single-wall carbon nanotubes (SWNT) filled with fullerene (Ceo) were discovered by Smith et al. [1] and synthesized in vacuum. The peapod have attracted much attention due to unique properties as a new carbon related material in recently decade. These 'peapods' generally occur as highly ordered long chains with the same ~10 A intermolecular spacing as in the fee solid. Cgo is a strong electrophile, so one might expect the surrounding tubes to become hole doped. Therefore, Qomicron-Qomicron and Qomicron-SWNT interactions are expected to influence structure, dynamics, and electronic properties.[2, 3] In this experiment, field emission (FE) of peapod emitter measured and compared with the result of pristine SWNTs.
