Those materials in which number of holes in valence band is equal to number of electrons in conduction band are called

Compare valence band and conduction band.

Statement-1: In semiconductors current is obtained due to motion of electrons and holes. Statement-2: Breaking up of covalent bond produces holes in valence band and electrons in conduction band.

Number of electrons = Number of holes in conduction band and valence band. So that solid is

A material with overlapping conduction and valence bands will be

A Both Valance band and conduction band can accommodate equal number of electrons. B. Conduction band has less energy then Valance band.

If the temperature of semiconductor is increased the number of electrons in the valence band will

Write the definition of valence band and conduction band.
