Question

The energy gap between the valence band and the conduction band for a material is 6 eV. The material is (A) an insulator (B) a metal (C) an intrinsic semiconductor (D) a superconductor

Tardigrade Admin · Accepted Answer

Insulators have large energy gap between valence and conduction bands (about 6 eV), while semiconductors have a smaller one and conductors, the smallest energy gap.
