Unformatted text preview: oltage (dV). dQ’ = Nd dxn = Na dxp. After some algebra, C’ = εs/W, where εs is the semiconductor dielectric constant and W is the total depletion width. This means that the depletion- (layer) capacitance is the same as that of a parallel- plate capacitor. 8 In a p+n diode, the depletion layer of the p- semiconductor is very small. Most of the electric field and...
