Conduction band

Vedclass · Answer

(B) When the temperature of a semiconductor is raised or an external electric field is applied,valence electrons gain sufficient energy to jump across the forbidden energy gap from the valence band to the conduction band. Once in the conduction band,these electrons are free to move through the crystal lattice,thereby contributing to electrical conduction. Therefore,the state of the energy gained by these electrons is referred to as the conduction band.

The state of the energy gained by valence electrons when the temperature is raised or when an electric field is applied is called as:
