When a forward bias voltage of 0.64 V was applied to an abrupt silicon pn-junction at 300 K, the hole diffusion current density measured J, (Xn) = 3.88 A/cm². Assume n=1*100 cm, Dr= 25 cm²/s, D = 10 cm /s, In = tp = 5x10-7s, and & = 11.7. (i) Starting from the expression for Jo, determine the dopant concentration at the n-side. (i) What is the value of the minority carrier hole concentration at the edge of the depletion region? (iii) If the total diode current density measured J= 4.49 A/cm², compute the value of electron diffusion current density Jn(-xp).
