In a n type silicon, which of the following statement is true?

The correct answer is Option (4) → holes are minority carriers and pentavalent atoms are the dopants

An n-type semiconductor is made by doping silicon with a pentavalent element (As, Sb, P). Four of its five valence electrons form bonds and the fifth is almost free, so the donated electrons far outnumber the thermally generated holes. Electrons are the majority carriers and holes the minority carriers.

NCERT (2026-27):
Extrinsic Semiconductor – “… Hence in an extrinsic semiconductor doped with pentavalent impurity, electrons become the majority carriers and holes the minority carriers. These semiconductors are, therefore, known as n-type semiconductors.”
