WebAug 4, 2024 · In an extrinsic semiconductor, electron density n and hole density p are related by the mass action law: np = ni 2. The two densities are also governed by the law of neutrality. Thus, a semiconductor is required to be electrically neutral i.e. the magnitude of negative charge density must equal the magnitude of positive charge density. WebWe take a P type semiconductor (Holes-Maj, Electrons-Min) and an N type semiconductor (Holes-Min, Electrons-Maj) and join them together. Since there is a conc. gradient, Electrons and holes start diffusing from N to P, and P to N respectively. As they do so, the depletion region becomes more +ve on the N side, and -ve on P side, creating an ...
