Consider a pn junction in equilibrium at room temperature (T = 300 K) for which the doping concentrations are NA = 1018/cm3 and ND = 1016/cm3 and the cross-sectional area A = 10-4 cm2. Calculate pp, np, nn, pn, V0, W, xn, xp and QJ.
We can use ni = 1.5×1010/cm3 for the calculations:
We obtain the value of V0 by deducing from the equation:
