Silicon ribbons pave the way for graphene-like sheets

There is one thing that graphene can’t do and that is to fit easily into the silicon-based electronics industry. And while graphene based chips hold much promise, it’s hard to see chip makers re-tooling to use carbon instead of silicon in the near future.

That’s why a number of groups have become to look at the possibility of making silicon versions of grahene, a material called silicene. Silicon nanowires made their first appearance in 2005. And now Christelle Leandri at the Center for Interdisciplinary Nanoscience in Marseille, France, and a few buddies have made silicene for the first time, albeit in the form of stripes or nanoribbons.
