Electronics background
... At the junction of the p-type and n-type some of the electrons will migrate from the ntype into the holes in the p-type. This creates a region at the junction without any charge carriers i.e. an insulating layer. As electrons have left the n-type it becomes positively charged near the junction whil ...
