摘要:
利用全丝网印刷技术制备四针状氧化锌表面传导场发射器件，并测试其场发射性能。扫描电镜表明所合成的四针状氧化锌均匀地沉积在阴栅间隙，形成传到层。场发射测试结果表明，随着阳极电压增高，阳极电流增大，开启电压降低。当阳压为2400V时，器件的开启电压降为70V；栅压为120V时，器件最高亮度达550 cd/m2。对器件进行450分钟的电流稳定性跟踪测量，其阳极电流波动在4%以内，表明该器件具有良好的场发射稳定性。
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.
