The field enhancement factor for a cylindrically symmetric structure is obtained using an electrostatic model based on a self-validating algorithm. The correct 0 V equipotential line is calculated such that it matches the surface of the given structure.
In this work we investigate the effect of various structural geometry on the field enhancement factor of an individual carbon nanotube (CNT) field emitter. We employ a computational model, that has been experimentally verified, to investigate the influence of system component geometry. Our results show that, in certain cases, the influences of support length and anode-cathode separation distance are...
