Problem 4: Narrow-Base Diode Consider an ideal pn* step-junction Si diode maintained at 300K with cross-sectional area A = 104cm2. The doping concentration on the p-type side is Na= 1017 cm3 (uncompensated). (The n-type side is degenerately doped.) The electron recombination lifetime in the p-type region is tn = 10-6 s. The width of the quasi-neutral p-type region is 1 um, for VA=0 V. a Is this a narrow-base diode? Justify your answer. b) Calculate the diode saturation current Io....
