A Si pn-junetion has a cross seetional area of 1x10 c, at 300xa forward bias voltage of
4v results in 1.5x10t cm excess holes at the edge position of the depletion region in the
a-side of the junction, assuming a hole lifetime of 1 pe, then the hole current at a
penetration depth of 5 um in the neutral n-region will be;
O S460e5 A
O 5694e 6 A
O 1.66Se 8 A
O 2574e 6 A
O 1800-6A
