Consider a silicon diode at T=300 K with Nd = 4 × 1016 cm?3 , Na = 1 × 1015 cm?3 , Dn = 25 cm2/s, Dp = 10 cm2/s, ?n = 5 × 10?7 s, ?p = 10?7 s, A = 10?3 cm2 , ni = 1.5 × 1010 cm?3 , r = 11.7. (1) Determine diffusion capacitance and junction capacitance at (a) Va = 0.4 V; (b) Va = 0.6 V. (2) At what voltage the two capacitances are equal? Hint: the solution cannot be found analytically, so you have to do it approximately, e.g. by trial and error, graphically, using matlab, etc
