    Many-body transitions in a single molecule visualized by scanning tunnelling microscopy

    A single-particle model is usually used to interpret the tunnelling spectra of molecules on surfaces, but scanning tunnelling microscopy now shows that many-body effects can occur in a single molecule.

    Suppression of electron–vibron coupling in graphene nanoribbons contacted via a single atom

    Graphene nanostructures, where quantum confinement opens an energy gap in the band structure, hold promise for future electronic devices. To realize the full potential of these materials, atomic-scale control ...
