I guess my most general question would be:
Given a P/N junction. Let's say two circular discs, one P one N. There obviously exists some Vgap, and applying some voltage across it excites the electrons, then it emits light (very basic LED or something).
Now, what if you took a piece of wire, and coiled it, and put it around the diode. Let's say for arguments sake you theoretically only put the coil around the N part.
Now you run a current through the coil. This creates a B field in the +-Z direction for the N part, which, since semiconducting, creates a current in the Lz direction (loop about the Z axis). Now this current doesn't really go anywhere, right? It just spins around and around.
What I'm wondering is : Would this induced loop current have ANY effect on the Vgap energy (the barrier). I'm figuring perhaps there's something due to scattering, or something else.
I have a feeling it would really only change the free electrons, which might change the intensity, but not the energy of the gap.
Can someone tell me?
