Abstract :
We fabricated diamond-like-carbon (DLC) coated knife edge field emitter array (KEFEA) on the (110) oriented silicon wafer. The fabricated KEFEA have above six hundreds times of aspect ratio. Then we coated the KEFEA with 300 Å thick DLC film by PECVD method. And we measured the emission current from the KEFEA under vacuum pressure of around 2×10-7 torr. The threshold voltage of the DLC-coated KEFEA lowered about 200 V compared with the bare Si KEFEA. By coating the DLC film, its emission stability was dramatically improved. A simulation on the emitter has been performed by using MAXWELL software
