Answer to Question #76093 in Electric Circuits for nancy

Question

State, with reasons, whether the following statements are True or False
Reverse biasing of a semiconductor junction diode increases its energy band gap

Answer 1

When semiconductor junction is reverse biased i.e. negative terminal of the battery connected to the P type region and positive terminal connected to the n type region. Then holes are attracted to the depletion layer in the n type region and electron are attracted to the depletion layer in the p type region . So, this widen up the depletion layer and increases the energy band gaps.


Answer: Statement is ‘True’.
