At room temperature, a p-type semiconductor has

At room temperature, a p-type semiconductor has
  1. equal number of free electrons and holes.
  2. large number of free electrons and few holes.
  3. large number of holes and few electrons.
  4. no electrons or holes.

Solution

Concept: P-type semiconductor is doped with trivalent impurities which generate acceptor levels near the valence band. Therefore, the majority carriers are holes and the minority carriers are electron.
