Chapter 1, Problem 1.12EP

A pn junction diode and a Schottky diode both have forward−bias currents of 1.2 mA. The reverse−saturation current of the pn junction diode is $I_S=4\times {10}^{-15}\text{A}$ . The difference in forward−bias voltages is 0.265 V. Determine the reverse−saturation current of the Schottky diode. (Ans. $I_S=1.07\times {10}^{-10}\text{A}$ )
