Electron emission characteristics of a triode surface-conduction field emission display were simulated with finite element analysis method and MATLAB. The parameters of the display structure were optimized based on the simulation results. Field emission from the carbon nanotubes and ZnO nanotetrapod compound cathodes were also simulated and studied.
Field emission properties of a planar triode structure with double cathodes have been investigated. ZnO nanotetrapod emitters mixed with carbon nanotubes(CNTs) were fabricated by the screen-printing method. The potential distribution, electron trajectoryies distribution and current density distribution were simulated in detail with CST PARTICLE STUDIO code. A higher field emission density current...
In the previous study, the surface-conduction field emission (SCFE) structure has been proposed. The SCFE structure can be fabricated very easily with low cost. However, the electron beam diverges seriously in a SCFE structure. To improve the focus performance of electron beam, a SCFE structure with focus electrode is proposed in this paper.
A double gate structure ZnO Field Emission Display (ZnO-FED) is proposed. In this kind of structure, a planar gate electrode is printed onto the cathode plate, it is used to modulate the conductive current from the ZnO emitters; a mesh grid with MgO layer is placed above the cathode plate and as the other gate electrode. Compare to the normal planar triode structure ZnO-FED, the focus performance...
