Abstract :
In this paper, we demonstrate an easy way to fabricate the power controllable field emission lamps by computing simulation. Based on our previous research, we use SolidWorks® to build a three dimension model and using Comsol Multiphysics 4.1a to calculate the electric field distribution on a straight 304 stainless steel filament with 1mm radius cathode and on it we cut a notch with various lengths. Simulation results show that the electric field on the notch is increased with notch length. By adjust the notch length on the cathode; we can control the power of the field emission lamps.
