AbstarctWe have fabricated a new three-terminal lateral field emitter structure in which the anode current is limited by the channel current of undoped region. The new device exhibits an excellent stability of the emission current. The field emission characteristics of fabricated device have two modes. In the first mode below 89 V, the mechanism of emission is identical to that of conventional poly-Si emitters and, in the second mode above 89 V, the emission current is limited by the inversion charges in the channel, so stable anode current is maintained. Furthermore, the fabrication process of the device is very simple.

AbstractWe have fabricated poly-Si, Si, and Ti-silicide field emitter arrays employing in-situ vacuum encapsulated lateral field emitter structures and investigated the field emission characteristics such as turn-on voltage, emission current density, and the stability of emission current. Although poly-Si and Si emitter have almost identical turn-on voltages, Si emitter has a sharper turn-on than poly-Si emitter due to its uniform surface. The current densities of poly-Si, and Si emtter are 0.47, 0.43 μA/tip respectively at anode to cathode voltage of 90 V. The turn-on voltage and current density of Ti-silicide emitter are about 31 V, and 1.81 μA/tip at VAK of 90 V. The data of the normalized current fluctuations indicate that Ti-silicide emitter has the most stable current.Our experiment shows that Ti-silicide is most promising among these three materials due to its low work function, uniform surface, and the stable characteristics.
