    • A field emitter array comprises a plurality of cathode electrodes and an anode electrode disposed opposite to the plurality of cathode electrodes. And the anode electrode is provided with a plurality of protrusions having a cap material disposed on the tip of each protrusion. A voltage below a designated value is applied between a gate electrode and the cathode electrodes, and electrons are released only from a cathode electrode with a low emission start voltage. When the electrons are emitted to the cap material provided on the protrusions, the cap material is sputtering-evaporated and is affixed to the cathode electrode. Then a cap is disposed on the each of the cathode electrodes. Then, the emission properties between each cathode electrode are consequently rendered uniform, thereby increasing the emission start voltage and maximum applied voltage of the overall field emitter array.
    • 场发射器阵列包括多个阴极电极和与多个阴极电极相对设置的阳极电极。 并且阳极电极设置有多个突起,其具有设置在每个突起的尖端上的盖材料。 在栅电极和阴极之间施加低于指定值的电压,并且仅从具有低发射起始电压的阴极释放电子。 当电子被发射到设置在突起上的盖材料时,盖材料被溅射蒸发并且固定到阴极电极。 然后在每个阴极上设置盖。 然后,各阴极之间的发射特性因此变得均匀,从而增加了整个场发射极阵列的发射开始电压和最大施加电压。
