Question

Based on the energy band description, a solid can be classified as insulator the energy gap between the valance band and conduction band is (A)  3 eV < Eg < 6 eV  (B) Eg > 6 eV (C) Eg < 3 eV (D) Eg =0 eV

Tardigrade Admin · Accepted Answer

In insulators, the forbidden energy gap is quite large. For example, the forbidden energy gap for diamond is 6 eV, which means that minimum of 6 eV energy is required to make the electron jump from the completely filled valence band to conduction band.

Q. Based on the energy band description, a solid can be classified as insulator the energy gap between the valance band and conduction band is

$3 e V < E_{g} < 6 e V$

$E_{g} > 6 e V$

$E_{g} < 3 e V$

$E_{g} = 0 e V$

Q. Based on the energy band description, a solid can be classified as insulator the energy gap between the valance band and conduction band is

3eV<Eg​<6eV

Eg​>6eV

Eg​<3eV

Eg​=0eV
