ABSTRACT

An analytical model for the potential barrier near the apex of an ultrathin edge field emitter is suggested. It is used for the numerical modeling of electron tunneling from the emitter. The results show that the conventional approximation of a uniform field near the edge is not proper for an ultrathin emitter. The suggested approach is more adequate for modeling of field emission from nano-sized cold cathodes.
