The size of the bandgap and the filling of the bands determine the material's fundamental electrical behavior: Material Type Band Structure Characteristic Typical Bandgap ( Egcap E sub g Engineering Examples Partially filled valence band or overlapping bands; no gap. Cu, Al, Au Semiconductors Filled valence band, empty conduction band at ; small gap. Insulators Filled valence band, empty conduction band; large gap. SiO2SiO sub 2 ), Diamond ( 4.
