MHT CET 2022 Physics question

Not in JEE Advanced syllabus

At room temperature, a p-type semiconductor has

(A)equal number of free electrons and holes
(B)large number of free electrons and few holes
(C)large number of holes and few electronsCorrect
(D)no electrons or holes

Answer: (C)

Solution

A p-type semiconductor is made by doping an intrinsic semiconductor with trivalent impurity atoms (acceptors). Each acceptor creates a hole, so at room temperature holes are the majority carriers (), while free electrons, generated only
