Periodic Deviations in the Schottky Effect

Abstract
The periodic deviations in the Schottky effect are recalculated in this paper. The same basic model is taken as in the work of Guth and Mullin, and of Juenker, Colladay, and Coomes. The difference between this work and the previous treatments is that WKB-type approximations are used. It is felt that these remove some of the uncertainties in the derivation. The results are essentially the same as those of Juenker, Colladay, and Coomes, except that the amplitude of the deviations found is about twice as large and has a slightly different dependence on the field.
