2.3 If, for a particular junction, the acceptor concentration is 10 17//cm 3' and the donor concentration is 10 16 cm², a) find the junction built-in voltage. b) Assume n;

= 1.5×10 10. 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. c) Calculate the magnitude of the charge stored on either side of the junction. Assume that the junction area is 100 µm².
