Which of the following current must be zero in an unbiased P N junction diode?

Options

  1. ACurrent due to majority charge carriers (both electrons and holes).
  2. BCurrent due to minority charge carriers (both electrons and holes).
  3. CCurrent due to majority and minority charge carriers.
  4. DCurrent due to majority and minority charge carriers (only holes).

Correct answer

B. Current due to minority charge carriers (both electrons and holes).

Step-by-step solution

In an unbiased PN junction diode current flow due to minority charge carriers (electron in the P -region and holes in the N -region).
