Screening and atomic-scale engineering of the potential at a topological insulator surface
P. Löptien, L. Zhou, J. Wiebe +5
The electrostatic behavior of a prototypical three-dimensional topological insulator BiSe(111) is investigated by a scanning tunneling microscopy (STM) study of the distrib…
Direct Measurement of Surface Transport on a Bulk Topological Insulator
Lucas Barreto, Lisa Kühnemund, Frederik Edler +7
Topological insulators are guaranteed to support metallic surface states on an insulating bulk, and one should thus expect that the electronic transport in these materials is domin…
Surface structure of Bi2Se3(111) determined by low-energy electron diffraction and surface X-ray diffraction
Diogo Duarte dos Reis, Lucas Barreto, Marco Bianchi +11
The surface structure of the prototypical topological insulator Bi2Se3 is determined by low-energy electron diffraction and surface X-ray diffraction at room temperature. Both appr…
Electron-phonon coupling-induced kinks in the sigma band of graphene
Federico Mazzola, Justin W. Wells, Rositza Yakimova +8
Angle-resolved photoemission spectroscopy reveals pronounced kinks in the dispersion of the sigma band of graphene. Such kinks are usually caused by the combination of a strong ele…
Direct view on the ultrafast carrier dynamics in graphene
Jens Christian Johannsen, Søren Ulstrup, Federico Cilento +11
The ultrafast dynamics of excited carriers in graphene is closely linked to the Dirac spectrum and plays a central role for many electronic and optoelectronic applications. Harvest…
Excitation of coherent phonons in the one-dimensional Bi(114) surface
D. Leuenberger, H. Yanagisawa, S. Roth +5
We present time-resolved photoemission experiments from a peculiar bismuth surface, Bi(114). The strong one-dimensional character of this surface is reflected in the Fermi surface,…
