Assertion: The number of electrons in a `p`-type silicon semiconductor is less than the number of electrons ina pure silicon semiconductor at room temperature. Reason: It is due to law of mass action.A. If both the assertion and reason are true and reason is a true explantion of the assertion.B. If both the assertion and reason are true but the reason is not true the correct explantion of the assertion.C. If the assertion is true but reason falseD.

Answer» Correct Answer - A According to law of mass-action, `n_(i)^(2)=n_(e)n_(h)` For `p`-type semiconductor, number of electrons is less than the number of electrons in a pure silicon semiconductor that is for `p`-type semiconductor, `n_(e) lt n_(h)`. |
