Material in which there is a very narrow gap between the conduction and valence energy bands are called: Answer: Semiconductor

A semiconductor has a small energy gap (band gap) between the valence band and the conduction band, typically around 1 eV. Because of this narrow gap, electrons can gain enough energy to move into the conduction band and conduct electricity.
