Semiconductor Electronics

For transistor action, which of the following statements is correct?

  1. A.Base, emitter and collector regions should have the same doping concentrations
  2. B.Base, emitter and collector regions should have the same size
  3. C.Both the emitter junction and the collector junction are forward biased
  4. D.The base region must be very thin and lightly doped✓

You have the answer. The worked solution — and why the other three were written — is part of a paid pack.
