A semimetal is a material with a very small overlap between the bottom of the conduction band and the top of the valence band. A semimetal thus has no band gap and a negligible density of states at the Fermi level.
A metal, by contrast, has an appreciable density of states at the Fermi level because the conduction band is partially filled.
