Options

  1. Aboth free electrons and holes
  2. Bneither free electrons nor holes
  3. Conly free electrons
  4. Donly holes

Correct answer

B. neither free electrons nor holes

Step-by-step solution

Depletion region in an unbiased semiconductor diode is a region consisting of immobile ions only. i.e. In depletion region, neither free elements nor holes exist.
