It seems to me to make intuitive sense that electrons would not easily move from p-type semiconductor to n-type semiconductor.
After all, the n-type already has an excess, and the p-type has a deficit.
So you must REALLY FLOOD the p-type with electrons, before the current spills over.
This would be the breakdown voltage of the diode.
Does this make sense?
@oscherler Of course they never bothered with intuitive explanations in my school coursework!
Which may help explain why I get people asking me about the "quantum model" of a transistor. Because electronics students do not always know what they have been taught. I have to tell people there is no such model. That a transistor is SOLID STATE physics, the physics of crystals.
