文摘

The results indicated the deficiency of the conventional roughness evaluation method on the field emission tendency. The micro-roughness is more suitable to evaluate the field emission property compared with macroscopic surface roughness. The hawking machining should not be used to improve the endurance voltage strength of electrode materials.
