1.) Based on Neamen - End of Ch. 7 Checkpoint Questions (a) Sketch the energy band diagram of the pn junction when a reverse-bias voltage is applied. [Hint: In equilibrium (at zero bias), the Fermi energies on each side of the junction are aligned. When the junction is biased, the diode is no longer in equilibrium; the Fermi energies are "misaligned" by an amount eAV where AV is the applied voltage.] (b) Describe what happens to the depletion region width and electric field when a reverse-bias voltage is applied to the pn junction. (c) Explain the source of the junction capacitance.
