Question
In a p-type semiconductor, the current conduction is due to
Correct Answer
Option A is the correct answer.
Detailed Explanation
In p-type semiconductors, the majority charge carriers are 'holes'. Holes are vacancies in the covalent bonds created by doping with trivalent impurities (Group III elements), and they behave as positive charge carriers. Electrons are the minority carriers in p-type semiconductors. Atoms and protons are part of the crystal lattice and do not directly contribute to current conduction in this manner.
Hint
The 'p' in p-type stands for positive, referring to the majority charge carriers.
