TL;DR: The existence of a bandgap opening in graphene is demonstrated, induced by the patterned adsorption of atomic hydrogen onto the Moiré superlattice positions of graphene grown on an Ir(111) substrate.

TL;DR: In this article, the electron dynamics of the topological surface state on a photoemission was investigated by temperature-dependent angle-resolved photo-emission, and the electron-phonon coupling strength was determined in a spectral region for which only intraband scattering involving the topologically surface band is possible.

TL;DR: Annealing experiments and density functional theory calculations demonstrate that the basal plane of the graphene stays intact and point to a graphene-mediated mechanism for the H-induced lifting of the reconstruction.

TL;DR: In this paper, the Raman spectra of topological insulator Bi2Te 3 films prepared by molecular beam epitaxy (MBE) have been measured by an in situ ultrahigh vacuum (UHV)-MBE-Raman spectroscopy system.

TL;DR: In this article, the authors investigate the interaction between the coronene molecule and pyrolytic graphite by using temperature-programmed desorption and show how entropic effects play an important role in governing the desorization kinetics for large molecules such as coronene and must be taken into account in order to derive a realistic binding energy.
