A field-emission cathode is fabricated with ZnO tetrapodlike nanoemitters. With a simple planar triode structure, a cathodoluminescent light source has been investigated. Because of the characteristics of surface-conduction electron-emission planar triode, this cathodoluminescent light source shows a very good performance. As experimental results show, the turn-on electric field is about 1 V/mum,...
In this paper, we study the influence of the ZnO nanostructures, gap between cathode and gate, resistance of ZnO layer, and the accelerate electric field on the ration of Ia/Ig. Fig.3 gives the variation of gate current and anode current with different cathode-gate distance. From these curves, the electron emission efficiency can be estimated.
In this paper, we calculated and compared the performance of three different structures of CNT-FED: a normal triode structure, a double-gate structure, and a structure with insulator channel. By calculating the electrical field and the electron trajectories, we found that the normal triode structure is easy to induce pixel-pixel interference; while the double-gate structure subtract the anode current...
