Analysis of nonuniform field emission from a sharp tip emitter of Lorentzian or hyperboloid shape
For a sharp tip emitter, due to the non-uniform emission feature and the electron beam expansion in the vacuum, it is difficult to precisely determine the average field enhancement factor β_c as well as the effective emission area S_eff for a single field emitter. In this paper, we conduct a numer...
