Question

Fermi energy level for intrinsic semiconductors lies

Answer 1

Fermi energy level

1. The maximum energy level that an electron can get at the absolute zero temperature is known as the Fermi Level.
2. This level lies in between the valence band and conduction band because at absolute zero temperature the electrons are all in the minimum energy state.

Intrinsic type

Explanation:

1. In the case of an intrinsic semiconductor, the hole's number in the valence band is equal to the electron's number in the conduction band.
2. Therefore, the possibility of occupation of energy levels in the conduction band and valence band is similar.
3. Therefore, the Fermi level for the intrinsic semiconductor lies in the middle of the bandgap.

Thus Fermi energy level for intrinsic semiconductors lies in the middle of the bandgap.
