Abstract :
In this paper, samples of RVC were surface treated under various conditions of argon-ion beam voltage, beam current and duration. Surface treatment duration varied from 3.5 minutes to one hour in length. The resultant self-assembled surface features, observed by Scanning Electron Microscopy (SEM), demonstrate improved field emission both by being geometrically-beneficial emission sources as well as because of induced modifications in sp2- and sp3-bonds at the surface.
