Application of the method of field desorption of sodium for studying carbon nanostructures on the surface of rhenium field emitter

Abstract

Field desorption microscopy was used to study the surface of the rhenium field emitter after its carbonization. Field electron and field desorption images of the surface after carbonation at adsorption of sodium atoms are obtained. On the basis on the analysis of modifications of the field electron and field desorption images of the surface at different values of the electric field we concluded that formation on the surface of the carbonized rhenium of bulk graphite nanostructures affects the emission processes.
