I want to know the answer to the following question:
What is the name for a layer of p-type semiconductor set between two n-type semiconductors?
All the background I'm provided with is that "This construction produces two p–n junctions: a base–emitter junction and a base–collector junction, separated by a thin region of semiconductor known as the base region (two junction diodes wired together without sharing an intervening semiconducting region will not make a transistor).". Is that enough to answer the question?
Answer: no
