AbstractThe charge distribution and electrostatic potential along 1 μm long single-walled carbon nanotube were investigated using quantum mechanical simulations under realistic field-emission experimental conditions. Single layer of carbon atoms were found to shield electric field at the tip where field penetration occurred strongly. This strong penetration resulted to nonlinear decrease of potential barrier for emission. This was found to be responsible for low threshold voltage other than well-known geometrical field enhancement factor.
