Field Emission Properties of Ni Nanocones Arrays Fabricated by Electrodeposition

摘要：

Ni nanocones field emission arrays (FEAs) were fabricated by electro deposition. Morphologies of the Ni nanocone arrays were investigated by scanning electron microscope (SEM). Field emission properties of these arrays were tested by a vacuum field emission measurement system.The Ni nanocone arrays had low turn-on fields of 5～6.7 V/μm(corresponding to an emission current of 1 μA) and large currents of 155～206 μA. The effects of nanocones size and alignment on field emission properties indicated that maybe the sharper the nanocones, the better the performance of Ni FEAs. It was shown that morphology of Ni FEAs is a significant important condition and should be studied further.
