Question

For intrinsic semiconductors, the Fermi energy is half way between the valence band and the conduction band.
True
False

Answer 1

Fermi level in intrinsic semiconductor. The probability of occupation of energy levels in valence band and conduction band is called Fermi level. At absolute zero temperature intrinsic semiconductor acts as perfect insulator. However as the temperature increases free electrons and holes gets generated.

Answer 2

According to the statement mentioned in the question that,

For intrinsic semiconductors, the Fermi energy is half way between the valence band and the conduction band.

This statement is completely true.

Because,it is just normal phenomenon of the different physical characteristics of the Fermi energy of different semiconductor materials available.
