Originální abstrakt

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.
