1924 O. Jespersen Philos.

1965 W. B. Burford & H. G. Verner Semiconductor Junctions & Devices vii. 91 All junctions in semiconductors are inherently rectifying. To make such a p-n junction into an operable rectifier, we merely attach leads to the p and n regions and protect the active element..by suitable encapsulation.
