-
There, a Dr. Poganski gave a beautiful demonstration that the selenium rectifier was not a Schottky barrier, but a p-n junction between p-type selenium and n-type CdSe, a true heterojunction - although that term did not exist yet.
-

-
The junctions between n- and p-type silicon act like valves, stopping current flowing in the wrong direction.
-
The junctions in a transistor are between bits of silicon doped to conduct electrons known as n-type material, because electrons are negatively charged, and p-type areas doped to conduct positively charged holes in the crystal lattice, which are places where electrons should be, but aren't.
