Abstract
The theory of field-stimulated exoelectron emission (FSEE) is developed for an electric field which varies with time. The exo current I at electric field E which is ramped from E = 0 at constant rate β is where e is the electronic charge, s is a frequency factor, n 0 is the number of electrons in the exo level with energy ϕ measured from the zero energy in a vacuum, and a is a constant the value of which may be derived from a knowledge of the interaction between the emitted electron and the surface. The emission equation for thermally stimulated exoelectron emission is solved numerically using published data, and conditions are determined for which FSEE may be expected. The data quoted for FSEE from borosilicate glass are reviewed. A room-temperature FSEE glow curve may not be possible from glass. However, a calculated glow curve at 77 K. is presented.
