Additionally, the mechanism of emission of electrons through channels forming in the dielectric material is described. For the purposes of analysis, the emitters were prepared by coating a tungsten tip with a layer of Epoxylite® resin. A high-resolution scanning electron microscope (HRSEM) was used to scan the tip profile and measure the coating thickness. Field electron microscope (FEM) and Field ion microscope (FIM) have been used to study both: the emission-current distribution and the emission-ions distribution from the composite emitters. Two forms of emission patterns have been observed: a multi-spot pattern, from the clean emitters with irregularity in the substrate, and a bright single- spot pattern, from coated emitters with a high substrate.
