Question

In semiconductors at a room temperature(a) The valence band is partially empty and the conduction band is partially filled(b) The valence band is completely filled and the conduction band is partially filled(c) The valence band is completely filled(d) The conduction band is completely empty

Answer 1

(a) the valence band is partially empty and the conduction band is partially filled

Answer 2

Answer:

In semi-conductors at a room temperature(a) The valence band is partially empty and the conduction band is partially filled.

Semi-conductors are neither conductors nor insulators but fall in between them, i.e. they allow electricity to pass through them only in certain conditions.

They can be classified into two major types: Intrinsic semi-conductor and Extrinsic semi-conductors.
