Abstract

The adaptability of field emitters in oxidizing environment is an important issue for practical applications. Herein, the effect of ozone exposure on the field emission property of molybdenum (Mo) nanowalls was studied. Results indicate that Mo nanowall cold cathode shows strong resistance to high doses of atomic oxygen exposure. The immunity of Mo nanowalls to oxidizing environment was attributed to the protection of surface amorphous layer. Mo nanowall cold cathode could be a promising candidate for electron source used in oxidizing environment.
