Hi,
I'm studying the p-n junction and I'm a little confused about the depletion layer that forms. I understand how electrons and holes diffuse across the junction, recombine and leave charged ions but what I don't understand is why the ions remain fixed around the junction. Surely the positive ions in the n-type region will attract the free electrons remaining in that region further away from the junction, effectively causing the ions to diffuse evenly throughout the n-type region?
