In the depletion region of a pn junction, there is a shortage of_________________?
Correct answer: B. Holes and electrons
- A. Acceptor ions
- B. Holes and electrons
- C. Donor ions
- D. None of the above
Explanation
Near the junction, electrons and holes recombine, leaving a depletion region almost free of mobile carriers. Fixed donor and acceptor ions remain there, so the shortage is of holes and electrons.
