3. (40 pts) The capacitance of a silicon pn junction diode with an area 10° cm2 is measured. A plot of 1/C2 vs. the applied voltage Va is shown. The dashed line is extrapolated, continuing the data with a constant slope. From the junction capacitance formula and the dependence of W on Vbi-VA, one can obtain an equation for 1/C (a) If the diode is a one-sided junction, find the doping density on the low side from the measured (estimate...
