Silicene: It Could Be The New Graphene - Science News

Silicene: It Could Be The New Graphene - Science News: Speaking March 24 at a meeting in Dallas of the American Physical Society, Fleurence described a new recipe for making silicene. He and his Japanese colleagues grew a thin layer of silicon on top of the ceramic material zirconium diboride. X-rays shined on this thin layer of silicon revealed a honeycomb of hexagons similar to the structure of graphene.

This structure looks familiar to Guy Le Lay, a physicist at the University of Provence in Marseille, France. Last year, he created the first-ever silicene ribbons. Le Lay described these 1.6-nanometer wide stripes of honeycombed atoms, grown on top of silver, in the June 28 Applied Physics Letters.
