The roles of apex dipoles and field penetration in the physics of charged, field emitting, single-walled carbon nanotubes

Jie Peng, Zhibing Li, Chunshan He +8

A 1 $\mu$m long, field emitting, (5,5) single-walled, carbon nanotube (SWCNT) closed with a fullerene cap, and a similar open nanotube with hydrogen-atom termination, have been simul…
