  author={Min Wang and Chang Ming Li},
We investigate the peapod structure of C59N+@(10, 10) single-walled carbon nanotubes by simulation, and discover that the ball initial velocity could be controlled by the external impulse electric field, then becoming an oscillator, of which the period could be tuned in a relatively large range of 80–18 ps by adjusting the ball motion in the initial stage. The SWNT length could also be used to tune the period of the oscillator. Based on these results, two potential devices, controllable period…
