Properties of Semiconductors: Practice Problem & Solution

Which of the following statement is False? (2010 Pre)
The resistance of intrinsic semiconductor decreases with increase of temperature
Pure Si doped with trivalent impurities gives a p-type semiconductor
Majority carriers in a n-type semiconductors are holes
Minority carriers in a p-type semiconductor are electrons

Short Solution (Best for NEET):

To solve this problem, we apply the core principles of Properties of Semiconductors. Understanding the underlying formula is key to arriving at the correct answer below:

In an n-type semiconductor, electrons are the majority charge carriers and holes are the minority charge carriers. Therefore, the statement that majority carriers are holes is false.[cite: 1]
