Question#1 (10 points): Ideal Diode quiz Answer the following questions as concisely as possible. Assume the questions refer to an ideal diode. (a) Under reversed-biasing, what processes occur in the quasi-neutral regions adjacent to the depletion region edges? Is it drift and diffusion, diffusion and recombination, generation and diffusion, or generation and drift? (b) Why can’t the minority diffusion equation be used to determine the minority carrier concentrations currents in the depletion region of the diode? (c) What a priori justification is there for assuming recombination-generation throughout the depletion region? (d) What exactly is a wide based diode? (e) True or false: The reversed-bias saturation current may be alternatively viewed as arising from minority carrier generation in the quasi-neutral regions. (a) The relevant process is generation and diffusion . (b) The minority-carrier diffusion equations derive from an assumption that the electric field is equal to zero . Clearly, this is not true within the depletion region. (c) There is
