Question

The Fermi energy of an intrinsic semiconductor is undefined. True or false

Answer 1

yes Fermi energy is a semi conductor.

Answer 2

According to the question,

The Fermi energy of an intrinsic semiconductor is undefined.

This statement is completely true.

Fermi energy is a concept in the quantum mechanics,which denotes the energy difference between the highest and lowest energy state occupied by a single particle in absolute zero temperature.

Due to the instability of this energy difference, the Fermi energy of the semiconductors are also undefined.
