Question

How can the depletion width be measured experimentally?​

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.
