Question: Consider an abrupt Si pn' junction that has 10 acceptors cm on the p-side and 10 donors on the n-side. The minority carrier recombination

Consider an abrupt Si pn' junction that has 10" acceptors cm on

Consider an abrupt Si pn' junction that has 10" acceptors cm on the p-side and 10" donors on the n-side. The minority carrier recombination times are r=490 ns for electrons in the p-side and t=2.5 ns for holes in the n-side. The cross-sectional area is 1 mm. 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 (ra) of the diode and why are they different?
