the number of holes increases while that of electrons decreases. the number of electrons increases while that of holes decreases. the number of holes and electrons remains same. Both the number of holes and the number of electrons increase equally. |
Both the number of holes and the number of electrons increase equally. |
The correct answer is Option (4) → Both the number of holes and the number of electrons increase equally. In an n-type semiconductor, heating generates more electron-hole pairs (intrinsic carriers). Thus, both the number of electrons and holes increase equally. Correct option: Both the number of holes and the number of electrons increase equally. |
