[twinklealices]

in any junction diode or transistor...i don't understand the difference between minority charge carriers, majority charge carriers and the immobile charges that you see in the depletion region ..please explain??

If you need the definition of those terms, wikipedia will serve.
I think you want an explanation of some process, though.
If so, please be MUCH more specific about what you're looking for.
