Question
In P-type semiconductor, the majority carriers are-
The correct answer is
Holes
Therefore, holes are the majority carriers responsible for conduction, while free electrons are the minority carriers . The trivalent impurity atoms that introduce holes are called acceptor impurities because they 'accept' an electron from a semiconductor atom, creating a hole.
