Distinguishing attosecond electron–electron scattering and screening in transition metals Open
Significance Electron–electron interactions are among the fastest processes in materials that determine their fascinating properties, occurring on attosecond timescales on up (1 as = 10 −18 s). The recent development of attosecond angle-re…

Controlling the electronic structure of graphene using surface-adsorbate interactions Open
Hybridization of atomic orbitals in graphene on Ni(111) opens up a large energy gap of ≈2.8eV between nonhybridized states at the K point. Here we use alkali-metal adsorbate to reduce and even eliminate this energy gap, and also identify a…
