The carbon nanotube (CNT) cathode ionization gauge is simulated using SIMION 8.0 software. The results show that all movement electrons emitted from the heated filament electron source are restrained inside anode ionization guage. However, to the CNT cathode ionization gauge, a few escaped electrons cannot be collected by anode. These escaped electrons influence the effective electron path length...
The results of modeling and development of planar multielectrode current sources based on nanoscale carbon structures with the low-threshold field emission are described. Mechanism of low-threshold field emission can be explained by the model, which describes the efficiency of tunneling of electrons from the carbon film into vacuum due to the existence of nanoscale clusters of two phases of DLC -...
