2. Derive the narrow base ideal diode equation (show all the procedures) in the dark and light. In this case, the lengths of p- and n-side regions are shorter than the diffusion lengths of electron and hole. Both ends of the diode have metallurgical contacts, so assume the excess carrier at the ends of the diode is zero. In the light, assume generation rate (G) is constant in the entire region, and the length of depletion region is W. Neglect the recombination at the depletion region. $W_p$ $W_n$ p n Excessive carrier at both ends of the diode = 0
