Stanene[1][2][3] is a topological insulator, which may display dissipationless currents at its edges near room temperature. It is composed of tin atoms arranged in a single layer, in a manner similar to graphene.[4] Stanene got its name by combining stannum (the Latin name for tin) with the suffix -ene used by graphene.[5] Research is ongoing in Germany and China, as well as at laboratories at Stanford and UCLA.[6]
The addition of fluorine atoms to the tin lattice could extend the critical temperature up to 100 °C.[7] This would make it practical for use in integrated circuits to make smaller, faster and more energy efficient computers.
