That's the thing I don't understand though. How come the voltage from the battery is not enough to break down the depletion zone during reverse bias? Both the internal electric field from the depletion zone and external electric field from the battery are in the same direction during reverse...
Hello!
I was just having a hard time understanding how reverse bias works for a p-n junction. Put simply, why don't electrons just diffuse back into the n-type semiconductor during reverse bias, thus generating current? I was thinking maybe it's got something to do with energy levels, but I'm...
