Abstract :
In this paper, we have studied the contact effect on the field emission properties of ZnO nanostructure printed on various substrates to understand emission performance more exactly. Here we demonstrated the field emission properties from the tetrapodlike ZnO nanostructure screen printed on Ag, carbon nano fiber (CNF)/Ag substrate respectively. The ZnO nanostructure is produced by chemical vapor deposition. Field emission properties were measured using a diode structure configuration, and the contact behavior between ZnO emitter and these substrates were also observed by scanning electron microscopy (SEM).
