MHT CET 2022 Physics question

Not in JEE Advanced syllabus

In a p-type semiconductor,

(A)holes are majority carriers and trivalent atoms are dopantsCorrect
(B)electrons are majority carriers and pentavalent atoms are dopants
(C)electrons are majority carries and pentavalent atoms are dopants
(D)holes are minority carries and trivalent atoms are dopants

Answer: (A)

Solution

A p-type semiconductor is made by doping pure silicon/germanium with trivalent (acceptor) atoms such as B, Al, Ga or In. Each acceptor creates a hole, so holes are the majority carriers and electrons are the
