Consider an abrupt Si pn + junction that has 1015 acceptors cm-3 on the p-side and 1019 donors on the nside.
The minority carrier recombination times are ?e = 490 ns for electrons in the p-side and ?h = 2.5 ns
for holes in the n -side. The cross-sectional area is 1 mm2. Assuming a long diode, calculate the
current, I, through the diode at room temperature when the voltage, V, across it is 0.6 V. What are V/I
and the incremental resistance (rd) of the diode and why are they different?
