(a) Draw the energy band diagram of a pn junction. Label the depletion region and the electric field in the depletion region. For an unbiased junction, discuss the movement of majority and minority carriers and the resultant current that may arise at equillibrium. (b) In a silicon pnp BJT, the emitter, base, and collector are doped with 10¹6 cm³ dopants, 5 x 10¹5 cm²³ dopants, and 2 × 10¹4 cm³ dopants, respectively. Draw the energy band diagram for the BJT at 300 K and label the width of the depletion zones.
