Original Abstract
The paper deals with the preparation and measurement of an experimental polymer graphite cathode that seems to be a promising and cheap source of electrons utilizing cold field-emission in high- and ultra-high vacuum. Polymer graphite seems to be a proper material as it contains a large amount of hybridized carbon withalowdegreeofsurfaceoxidationandsiliconmonoxide(SiO).Withintheframeofthiswork,aspecial experimental method of tip preparation has been designed and tuned. This method is based on ion milling insideadual-beamelectronmicroscopeenablingtoobtainultra-sharptipsofadiametersmallerthan100nm with a predefined opening angle. The charge transport within experimental samples is evaluated based on results provided by the noise spectroscopy of the total emission current in the time and frequency domains.
Keywords
