| Abstract: | By means of the computer simulation, the characteristics of field emission microtriodes are investigated in this paper. The finite method is used to solve the Poisson equation. Taking consideration of the space-charge effects, current y is obtained form Fowler-Nordheim equation, and the field at the cathode surface is calculated. The computed results show that the emitted current and the field enhancement depend upon geometrical factors,such as tip sharpness, tip height,significantly. |
