MHT CET 2022 Physics question

Not in JEE Advanced syllabus

The majority charge carriers in p-type and n-type semiconductor are respectively

(A)holes and electronsCorrect
(B)electrons and holes
(C)electrons and electrons
(D)holes and holes

Answer: (A)

Solution

A p-type semiconductor is formed by doping with a trivalent impurity (acceptor, e.g. B, Al), which creates holes; so holes are the majority carriers and electrons the minority carriers. An n-type semiconductor is formed by doping with a pentavalent impurity (donor, e.g.
