1. Due to a manufacturing error, the p-side of a p- junction has not been doped. If ND = 3 × 1016 cm-3, calculate the built-in potential at T = 300 K.
2. A pn junction with
experiences a reverse bias voltage of 1.6 V.
(a) Determine the junction capacitance per unit area.
(b) By what factor should NA be increased to double the junction capacitance?
