Problem 3.12

Calculate the built-in voltage of a junction in which the p and n regions are doped equally with atoms/cm3. Assume . With the terminals left open, what is the width of the depletion region, and how far does it extend into the p and n regions? If the cross-sectional area of the junction is 100 m2, find the magnitude of the charge stored on either side of the junction.
