A tunneling emitter that provides a mostly mono-energetic beam can be achieved using a square barrier which provides optimum current distribution when it is biased to a point where Fowler-Nordheim (FN) regime starts taking place. This is shown in Fig. 1. Since most mono-energetic emission is needed when eV(BE) approximately greater than Phi c, where Phi(c) is the collector barrier height, an optimum emitter has Phi(E) equals Phi(c) Plus Delta, where Delta is a small number which depends on the details of the barrier.
