Q. 9
A PN junction with cross-sectional area A=0.01cm^(2) has the following properties at 300 K :
(a) If using the asymmetric junction to make LEDs, derive the formula of calculating the injection
efficiency of P^(+)N LED.
(b) Find the injection efficiency according to the derived formula in part (a).
marksn_(i)=1.5\times 10^(10)cm^(-3) for this calculation.
c) calculate the reverse saturated c^(urrent of the pn junction if the intrinsic electron concentration ni)=1.5x10^(10 )cm^(-3) for this calculation. (please give detailed handwritten steps)
