'Bizarre' Nanobubbles Found In Strained Graphene

schliz writes "Physicists have observed 'bizarre' behaviour in graphene electrons that they say could make the material even more suitable to replace silicon in future electronic devices. When strained in a particular manner, nanobubbles formed on a sheet of graphene, within which electrons came to occupy particular, quantum energy levels rather than the usual, continuous range of energies in unstrained graphene. By controlling electrons' energy levels, researchers could control how easily they moved through graphene — in effect, controlling their conductivity, optical, or microwave properties."

Re:Technology reaching its limits?

Ten-twenty years ago, science fiction had this nifty thing called "nanotech" that did all sorts of neat stuff. We still don't have Drexler machines, grey goo, or atomic-scale Digi-Comps, but I've been working sub-100nM for around 10 years now, getting smaller every generation, so we're getting into the ballpark.

But science fiction is not to be outdone, a few years back I read "Pushing Ice"by Alastair Reynolds. They had femto-tech.
