Not to be confused with Stanine.

Stanene[1][2][3] is a topological insulator, theoretically predicted by Prof. Shoucheng Zhang's group at Stanford, which may display dissipationless currents[clarification needed] 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] Recent report of synthesis and study of optical properties of Stanene has been claimed by Nanostructures Engineering and MOdelling (NEMO) group at the Indian Institute of Technology Bombay.[7]

The addition of fluorine atoms to the tin lattice could extend the operating temperature up to 100 °C.[8] This would make it practical for use in integrated circuits to make smaller, faster and more energy efficient computers.
