There has been much work on electron emission. It has lead to the concept of the photon and new electron sources for imaging
such as electron microscopes and the rst formulation of holographic reconstructions [1-6]. Analytical derivations are important
to gain physical insight into the problem of developing better electron sources. However, to date, such formulations have su ered
by a number of approximations that have masked important physics. In this thesis, a new approach is provided that solves the
Schrodinger wave equation for photoemission from a single atom tungsten tip barrier or more generally, for photoemission from
a Schottky triangular barrier potential, with or without image potential e ects. We describe the system, then introduce the
mathematical derivation. We conclude with the applications of the theory.
