Jose Ramsey · Answer 1

To measure the depletion width of a pn junction, you need to measure capacitance. Capacitance is directly proportional to junction area, A, and inversely proportional to total depletion width, W (of both n and p sides) : You need to know the area to do this. The is that of the semiconductor.
