In an intrinsic (pure) semiconductor at T > 0:

  1. Only electrons
  2. No charge carriers
  3. Only holes
  4. Equal number of electrons (in CB) and holes (in VB)
Show answer and solution

Correct answer: D. Equal number of electrons (in CB) and holes (in VB)

Thermal excitation promotes electrons from valence band to conduction band, leaving holes. n_e = n_h = n_i (intrinsic carrier concentration). Both contribute to conductivity.
