Question
Classify each of the following as being either a p-type or a n-type semiconductor:
  1. Ge doped with In.
  2. B doped with Si.
✓

Answer

  1. Ge (a group 14 element) is doped with In (a group 13 element). Therefore, a hole will be created and the semiconductor generated will be a p-type semiconductor.
  2. B (a group 13 element) is doped with Si (a group 14 element). Thus, a hole will be created and the semiconductor generated will be a p-type semiconductor.
