It has been reported that field emission current from a carbide single crystal is much more stable than a tungsten field emitter. Recent progress in the development of stable carbide field emitters is reviewed.
Existence of an optimum flashing temperature is pointed out and a recently developed stabilizing technique of the carbide field emitter is introduced. It is also pointed out that the quality of the vacuum is still important for stable operation of a carbide field emitter.
