In an intrinsic semiconductor, the number of free electrons_____________?
Correct answer: A. Equals the number of holes
- A. Equals the number of holes
- B. Is greater than the number of holes
- C. Is less than the number of holes
- D. None of the above
Explanation
In an intrinsic semiconductor, electron-hole pairs are generated together, so every free electron is accompanied by a hole. Therefore, the electron and hole concentrations are equal.
