The theory of crystal rectifiers [chapter]

1995 World Scientific Series in 20th Century Physics  
Fowler (p. 434) discusses also a somewhat different model, namely, a layer of " bad" semi-conductor between a metal and a good semi-conductor. This is essentially the model we use in the second half of this paper. Fowler's treatment does not seem to us correct however; he assumes that the electrical double layer between the metal and bad semi-conductor would bring the levels of the latter into, equilibrium with the metal, as in fig. 1 (a) . Actually, however, since there are practically no
