For the pn junction for which NA =1018/cm, Np =1016/cm, A=10 cm?, and n; = Lp = 5 m, Ln = 10 m, Dp

 

For the pn junction for which NA =1018/cm, Np =1016/cm, A=10 cm?, and n; = Lp = 5 m, Ln = 10 m, Dp (in the n region) = 10 cm?/Vs, and Dn (in the p region) = 18 cm?/Vs. The pn junction is forward biased and conducting a current I = 0.1 mA. Calculate: (a) Is; (b) the forward- bias voltage V; and (c) the component of the current I due to hole injection and that due to electron injection across the junction. 1.5 x 101/cm, let
