Flows of Free Electrons and Holes

Flows of Free Electrons and Holes

  1. We have learned that there are 2 types of charge carrier in a semiconductor, the free electrons and the holes.
  2. The free electrons carry negative charge whereas the holes carry positive charge.
  3. If a potential difference is applied to a semiconductor, the electrons and holes will start to flow.
  4. The electrons will flow to the negative terminal whereas the holes will flow to the positive terminal.
  5. The video below explains how the free electrons and holes flow in an electric field.
