In a p-type semiconductor, the majority charge carriers and the minority charge carriers are respectively:
A. Ions and Holes
B. Protons and Electrons
C. Holes and Electrons
D. Electrons and Holes
Answer: Option C
Solution (By JKExamLibrary)
A p-type semiconductor is created by doping a pure semiconductor (like Silicon) with a trivalent impurity (like Boron). This creates a deficiency of one electron, creating a 'hole'. These positive holes vastly outnumber the thermally generated free electrons. Thus, holes are the majority charge carriers, and electrons are the minority charge carriers.
