Question

When the temperature of a n-type semiconductor is increased :

• A. Net negative charge is increased
• B. Minority carriers are decreased
• C. Net charge is zero
• D. None of the above is true

Answer 1

The correct option is D None of the above is true

When the temperature of a $\text{n -}$type semiconductor is increased, there increase the number of thermally generated electrons. As a result, the minority charge carriers increases. So, none of the given options are true.

The correct answer is the option (D)
