Energy spectrum of field emission

Abstract

Energy spectra of field emission were studied for various shapes of microroughness, i.e. a semiellipsoid, a cylinder with a semisphere on the top, a frustrum of cone with a semisphere on the top, a cone with an acute angle, etc., and also for various values of the nondimensional parameter M: M=/spl phi//sub 0//E/sub 0//spl middot/a, where a is the height of a microroughness.
