We're happy to announce a new section to Spintronics-Info: Research centers. We hope that this will be a comprehensive index for Spintonics related research centers around the world. If you know of some place we missed, please contact us.
In the meantime there are only two centers listed, but hopefully we'll start adding more soon.Â
A small ribbon made of the carbon honeycomb pattern found in graphite and nanotubes could display intriguing electronic properties and serve as a material for spin-based electronics (spintronics), researchers have predicted.
Steven Louie's group at the University of California at Berkeley, US, has now used ab initio calculations to show that ceratain carbon nanoribbons will display half-metallicity. The researchers calculated the electronic properties of graphene sheets (the single layers of hexagonally arranged carbon atoms found in graphite). Specifically, they looked at ribbons between 1.5 and 6.7 nm wide, with a zigzag border at each side (see image below).
