MHT CET 2023 Physics question

Not in JEE Advanced syllabus

When the conductivity of a semiconductor is only due to the breaking of the covalent bonds, the semiconductor is called

(A)donor
(B)intrinsicCorrect
(C)acceptor
(D)extrinsic

Answer: (B)

Solution

A pure semiconductor has no impurity; its conductivity arises only from electron-hole pairs generated when thermal energy breaks covalent bonds. Such a semiconductor is called intrinsic, option (b). Donor and acceptor are types of
