3.14 If, for a particular junction, the acceptor concentration is 10"/cm' and the donor concentration is 10"/cm", find the junction built-in voltage. Assumen, 1.5 x 10"/cm'. Also, find the width of the depletion region (W) and its extent in each of the p and n regions when the junction terminals are left open. Calculate the magnitude of the charge stored on either side of the junction. Assume that the junction area is 10 μm.
