Sketch the equilibrium band structure of pnp bipolar junction transistor (BJT). In point form, explain how the application of a bias voltage at the “base” changes the band structure that you have drawn and can be used to turn this device “on” and “off”. (a well-labeled equilibrium diagram will enable you to complete this without any further band-structure diagrams)
