Analytical Model for Electrical Field at Ultrathin Field Emitter

An analytical model is used to define the potential barrier near the apex of an ultrathin edge field emitter. It is used to numerically simulate electron tunnelling from the emitter. The results reveal that the typical approximation of a uniform field towards the edge is incorrect for an ultrathin emitter. Modeling field emission from nano-sized…
