The energy band gap is maximum in ……....

The energy band gap is maximum in …….

A

metals

B

insulator

C

super conductor

D

semiconductor

Text Solution

Verified by Experts

The correct Answer is:
B

insulator
Since forbidden gap in insulator is maximum means more than 3 eV. While the width of semiconductor is less than 3 eV and in metal and superconductor this width does not exist.
