Question
In a semiconductor, which of the following statement is correct?
✓

Answer

  1. p - n junction is electrically neutral.
Explanation:
Generally Si is a semiconductor. In p type semiconductor acceptor level lies near the valence band and each donor atom contribute one electron. p-n junction electrically neutral because total charge is zero.
