(A) Draw the energy band diagram for the p*np BJT and explain why the width of the emitter-base depletion zone is smaller than the width of the collector-base depletion zone. (b) Explain why it is important for the width of the base quasineutral region to be small compared to the minority carrier diffusion length in the operation of a BJT. (c) A Si pn junction has N₁ = 1018 cm³ on one side and N₂ = 5 x 10¹5 cm²³ on the other side. Draw the energy band diagram of the junction and deduce the built-in potential Vbi from the energy band diagram.
