ABSTRACT
This article presents a simulation study on the field emission characteristics of a single carbon nanotube (CNT) cathode in the triode structure. Computer Simulation Technology (CST) Particle Studio (M/s Jyoti Electronics, India) was used to simulate the triode characteristics in relation to geometrical parameters, position of the CNT, and applied gate and anode potentials. The results emphasize the significance of simulation-based optimization of structural parameters and field conditions prior to actual fabrication of CNT field emitters.
