What is the characteristic of a material with a large band gap (E_g > 3 eV)?
A
It cannot conduct electricity due to no electrons in the conduction band.
B
It allows easy movement of electrons from the valence band.
C
It has partially filled conduction and valence bands.
D
It exhibits high conductivity at room temperature.
