Category:Alloy junction transistors

English: Alloy junction transistors were an early construction technique for bipolar transistors. A germanium substrate formed the central base and (for a PNP transistor) pellets of indium were attached to each surface. These diffused into the base, forming p-type germanium and thus the emitter and collector.
