Physics - Semiconductors Question with Solution | TestHub

In an n-type semiconductor, pentavalent impurities are added to the pure semiconductor. Each pentavalent atom donates one electron to the conduction band. Therefore, electrons are the majority charge carriers and holes are the minority charge carriers.

The statement 'The majority carriers in n-type semiconductors are holes' is incorrect.

The resistance of an intrinsic semiconductor decreases with an increase in temperature because more electron-hole pairs are generated, increasing conductivity.

Doping pure silicon with trivalent impurities creates a deficiency of electrons (holes), resulting in a p-type semiconductor.

Answer: The majority carriers in n-type semiconductors are holes.
