Calculate the built-in voltage of a pn junction in which the p and n regions are doped equally with 7e15 atoms/cm³. Assume that n¡ = 1.5E10/cm³. With no external voltage applied, 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 µm², find the magnitude of the charge stored on either side of the junction.
