Sticky Note
When N-type semiconductor is heated?
  1. Number of electrons increases while that of holes decreases
  2. Number of holes increases while that of electrons decreases
  3. Number of electrons and holes remain same
  4. Number of electron and holes increases equally
Explanation
  • When an N-type semiconductor is heated, thermal energy generates electron–hole pairs.
  • The number of electrons increases in the conduction band.
  • At the same time, equal number of holes are created in the valence band.
  • Doping does not change this thermal generation behavior.
