Hello everyone. I have a couple of questions about the depletion region in the p-n junction 1) Why don't the negative ions on p-side of the depletion region donate their respective extra electrons to the positive ions on the n-side of the region so they can both be happy (This sounds kind of weird, because those ions exist due to the very same process that I'm now asking to reverse :p ) ? 2) After the application of a forward voltage, the width of the depletion region is reduced due to electrons falling in the +ve ions on the n-side, and holes falling in the -ve ions on the p-side, right? But those electrons and holes didn't exist independently, they belonged to their parent atoms that they've now left a net charge on to become a part of these new atoms. So in effect, those ions haven't been neutralized, only displaced to the right in n-side and to the left in the p-side. But this is not what theory says, so what am I missing here? Thank you for your time!
