Abstract

The dynode amplified carbon nanotubes (CNTs) field emission device proposed by MRL/ITRI is investigated via computer simulation. Particle-in-cell finite-difference time-domain (PIC-FDTD) method is used to study the effects of dynode on electron emission, amplification and movement. Simulation results of the emission current, the anode current, and the current density distribution of the CNT-FEDs, with and without the dynode structure, are compared. Results show that the dynode amplified CNTs field emission device improves the FEDs brightness and resolution.
