Depletion region has:
Correct answer: D. Neither holes nor electrons
- A. Electrons only
- B. Holes only
- C. Both electrons and holes
- D. Neither holes nor electrons
Explanation
The depletion region of a p-n junction contains neither free electrons nor holes. It is an area depleted of mobile charge carriers due to the diffusion of majority carriers from one side to the other. This creates a region with immobile ionized donor and acceptor atoms, resulting in a fixed internal electric field.Depletion region or depletion layer is a region in a P-N junction diode where no mobile charge carriers are present.

About Electronics
A p-n junction forms when p-type and n-type semiconductor regions meet, creating a depletion layer, barrier potential and rectifying action. The work covers forward and reverse bias, junction current, diode characteristics, and how a diode converts alternating current into pulsating direct current through half-wave and full-wave rectification.
