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

(A)extrinsic
(B)intrinsicCorrect
(C)p - type
(D)n – type

Answer: (B)

Solution

In a pure semiconductor, conduction arises only from electron–hole pairs created when thermal energy breaks covalent bonds; the number of electrons equals the number of holes. Such a pure semiconductor is called intrinsic, option (B). An
