Abstract :
The field emission characteristics from the SiC micro powders with sharp edge are investigated. The edge of the SiC powder works as the field emitter. The emission current follows the Fowler-Nordheim relationship. An excellent emission stability in short term is confirmed. These results show that the SiC powder is a good candidate for field electron source.
