An example of a semi-metal is

A semi-metal is a material with a very small overlap between the bottom of the conduction band and the top of the valence band. According to electronic band theory, solids can be classified as insulators, semiconductors, semimetals, or metals. The semimetals or metalloids are listed as boron, silicon, germanium, arsenic, antimony, tellurium, and polonium.
