Consider a p-n junction diode having the characteristic \[ \rm i = i_{0} ( e^{\frac{eV}{kT}} - 1 ) \] where \( \rm i_{0} \) = 20 μA. The diode is operated at T = 300 K. (a) Find the current through the diode when a voltage of 300 mV is applied across it in forward bias. (b) At what voltage does the current double?
