In an NPN transistor, the connection between base and collector is a PN junction, so as you might expect it shares its properties with the PN junction in a diode.

A couple of books by Cletus Kaiser, The Diode Handbook and The Transistor Handbook, take you back to basics on these fundamental building-block components. The book on diodes contains sections on ...

From Ebers-Moll model to quantum thermal transistors. We focused on a quantum thermal transistor consisting of two quantum two-level systems (qubits) interacting with a three-level system (qutrit ...

In the early days, PNP bipolar transistors were common, but the bulk of circuits you see today use NPN transistors. As [Aaron Danner] points out, many people think PNP transistors are “backwa… ...
