semimetal

/se.mi.meˈtaw/ noun

A solid of which the conduction and valence band overlap slightly in energy.

Word Origin Built from Latin semi- 'half' and Greek metallon 'metal' — so a semimetal is literally 'half-metal.' It's an element that has some properties of metals and some of nonmetals, like silicon or arsenic. The semi- prefix also gives us semicircle, semiconscious, and semifinal — all things that are halfway there. And metallon is the same root that gives us metallic and metallurgy.

noun A solid of which the conduction and valence band overlap slightly in energy. countable
