If the \(\mathrm{p}-\mathrm{n}\) junction diode is unbiased,
- A n-type side has lower potential than p-type side.
- B n-type side has same potential as p-type side.
- C An electric field is established at the junction such that n side is at positive voltage relative to p -side.
- D The potential across the junction is such that \(p\)-side is at positive voltage relative to n -side
Answer & Solution
Correct Answer
(C) An electric field is established at the junction such that n side is at positive voltage relative to p -side.
Step-by-step Solution
Detailed explanation
n-type side has lower potential than p-type side: This is correct. The built-in electric field causes the p -side to have a higher potential than the n -side.
