Question

Which one of the following statement is false? 

(a) Pure Si doped with trivalent impurities gives a p-type semiconductor. 

(b) Majority carriers in a n-type semiconductor are holes. 

(c) Minority carriers in a p-type semiconductor are electrons. 

(d) The resistance of intrinsic semiconductor decreases with increase of temperature. 

Answer 1

The correct option is (b) Majority carriers in a n-type semiconductor are holes. 

Explanation:

In a n-type semiconductors. electrons are majority carriers and holes are minority carriers.
