Fabrication and testing process is as follows: firstly, Ag electrode is printed on the silicon substrate with a screen-printing method, 4 hours should be taken for barking at 550 °C. In the second step, cold cathode emitter should be prepared by the combination of carbon nanotubes (CNTs) and ZnO's slurry at a certain proportion. With the same screen-printing method, we print the composite emitter...
Using the tunneling effect under high electric field, field emission cold cathode could obtain an emission current which is large enough. In this paper, we reported the large field-emission from CNTs and ZnO tetrapods composited field emitters. Screen-printing method is used in our experiment and more than 15 mA field-emission current is obtained with 0.5 mm gap.
In this letter, an improved planar triode with ZnO nanopin field emitters has been proposed. Comparison with a conventional planar triode, a layer of ZnO nanostructures is deposited between the cathode and gate electrode. These ZnO nanostructures are used as field emitters. Because both electrodes and ZnO layer can be deposited with screen-printing method, the fabrication process of an improved planar...
Field emission display inherits excellent display qualities of traditional CRT and is a prospective flat display panel. Traditional normal gate FED consists of front and rare glass substrates, using spacer matrix for maintain fixed gap. Compared with diode structure, the modulation voltage is lower in triode structure because of the shorter gap between gate and cathode. However, in a normal gate triode,...
