Question

In an intrinsic semiconductor ,fermi level is

• A. closer to valence band
• B. midway between conduction and valence band
• C. closer to conduction band
• D. none of the above

Answer 1

The correct option is B midway between conduction and valence band

In an intrinsic semiconductor, the semi level lies mid way of conduction and valance bond. In an intrinsic semiconductor, no of holes in valance bond $=$ no of electrons in conduction bond.
