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.
