a) For the circuit shown in Fig \( Q 6 a \), determine \( V_{D}, V_{R} \) and \( I_{R} \) if the diode is a non-ideal Silicon diode. [10 marks] Fig Q6a b) Refer to the carrier concentrations in each of the layers of a Si and a GaAs diode as shown in Table \( Q 66 \), calculate the built in potential at room temperature for each diode. Assume that the thermal voltage is \( 26 \mathrm{mV} \). [10 marks]
