CALCULATION OF AUTOEMISSION STRUCTURES IN THE PROGRAM ELCUT
Of great interest one have in investigation field electrons emission by carbon and diamondlike thin film, fulleren and nanotubes. The cold cathodes with low electric field threshold emission have been attracted more and more attentions for its important applications in vacuum electronic devices. However, the present cold cathodes do not have so good performance, stability emission that it can be considered as commercial application on large scale. All of that need to be considered large number of geometric models device. Complicacy of the field distribution and particles flow do not fall under analytical solution. One need numerical simulation. The authors perform of used the soft ELCUT for numerical estimation any parameters of diode and triode geometry with field emission cathode like the geometric field enhancement, nonuniformity this parameter on surface area of emitter, intensity of the ions flow from different area volume of the device.
