摘要:

利用全絲網印刷技術制備四針狀氧化鋅表面傳導場發射器件，并測試其場發射性能。掃描電鏡表明所合成的四針狀氧化鋅均勻地沉積在陰柵間隙，形成傳到層。場發射測試結果表明，隨著陽極電壓增高，陽極電流增大，開啟電壓降低。當陽壓為2400V時，器件的開啟電壓降為70V；柵壓為120V時，器件最高亮度達550 cd/m2。對器件進行450分鐘的電流穩定性跟蹤測量，其陽極電流波動在4%以內，表明該器件具有良好的場發射穩定性。

Abstract:

Surface-conducted field emission devices based on tetrapod-like zinc oxide (T-ZnO) emitter have been successfully fabricated by screen-printing, and the field emission properties were investigated. The scanning electron microscope images showed that the as-synthesized T-ZnO deposited uniformly in the gap between cathode and gate electrode forming conducting layer. The field emission measurement results showed that with the increases of anode voltage, anode current of the device became larger, while turn-on voltage became smaller. The turn-on voltage was 70V when the anode voltage was set to 2400V. The maximum brightness of the device reached 550 cd/m2 when the gate voltage was 120V. A measurement of the emission stability was carried out, and the emission current fluctuation was smaller than 4% during the 450min, which indicated that the field emission device had a good field emission stability.
