Simulation of Field-emission Cathodes for High Current Electron Injectors
From the prospect of the high average current electron injectors, the most important advantage of the fieldemission cathodes is their capability to generate very large current densities. Simulation of field-emission cathodes is complicated by the large range of spatial dimensions: from sub-micron scale, for a single field-emission tip, to millimeter scale, for a field-emitter array. To overcome...
متن کاملEnhanced field electron emission properties of hierarchically structured MWCNT-based cold cathodes
Hierarchically structured MWCNT (h-MWCNT)-based cold cathodes were successfully achieved by means of a relatively simple and highly effective approach consisting of the appropriate combination of KOH-based pyramidal texturing of Si (100) substrates and PECVD growth of vertically aligned MWCNTs. By controlling the aspect ratio (AR) of the Si pyramids, we were able to tune the field electron emis...
متن کاملElectron field emission properties of tetrahedral amorphous carbon films
The electron field emission of tetrahedral amorphous carbon ~ta-C! films deposited by filtered cathodic vacuum arc is reported. The ta-C films were found to have a threshold field ranging from 18 to 28 V mm, depending on the sp content. The nitrogenated ta-C ~ta-C:N! films show a lower threshold field of 12 V mm as compared to the ta-C films. The threshold field appears to be dependent on the f...
متن کاملThe Electron Field Emission Properties of Ag-SiO2 Nanocomposite Layers
In this work, Ag-SiO2 nanocomposite layers were synthesized by introducing Ag nanoclusters into thermally oxidised SiO2 layers, using ion implantation. The field emission (FE) properties of these layers were studied and correlated with the results from atomic force microscopy and with transmission electron microscope measurements. These nanocomposites exhibit good FE properties and give an emis...
