Midgap states and band gap modification in defective graphene/h-BN heterostructures
B. Sachs, T. O. Wehling, M. I. Katsnelson +1
The role of defects in van der Waals heterostructures made of graphene and hexagonal boron nitride (h-BN) is studied by a combination of ab initio and model calculations. Despite t…
Phonon-pump XUV-photoemission-probe in graphene: evidence for non-adiabatic heating of Dirac carriers by lattice deformation
Isabella Gierz, Matteo Mitrano, Hubertus Bromberger +11
We modulate the atomic structure of bilayer graphene by driving its lattice at resonance with the in-plane E1u lattice vibration at 6.3um. Using time- and angle-resolved photoemiss…
Ferromagnetic two-dimensional crystals: Single layers of K2CuF4
B. Sachs, T. O. Wehling, K. S. Novoselov +2
The successful isolation of graphene ten years ago has evoked a rapidly growing scientific interest in the nature of two-dimensional (2D) crystals. A number of different 2D crystal…
Adatoms and clusters of 3d transition metals on graphene: Electronic and magnetic configurations
T. Eelbo, M. Waśniowska, P. Thakur +8
We investigate the electronic and magnetic properties of single Fe, Co, and Ni atoms and clusters on monolayer graphene (MLG) on SiC(0001) by means of scanning tunneling microscopy…
Doping Mechanisms in Graphene-MoS2 Hybrids
B. Sachs, L. Britnell, T. O. Wehling +6
We present a joint theoretical and experimental investigation of charge doping and electronic potential landscapes in hybrid structures composed of graphene and semiconducting sing…
Local Gating of an Ir(111) Surface Resonance by Graphene Islands
S. J. Altenburg, J. Kröger, T. O. Wehling +3
The influence of graphene islands on the electronic structure of the Ir(111) surface is investigated. Scanning tunneling spectroscopy (STS) indicates the presence of a two-dimensio…
Multi-scale magnetic study on Ni(111) and graphene on Ni(111)
L. V. Dzemiantsova, M. Karolak, F. Lofink +9
We have investigated the magnetism of the bare and graphene-covered (111) surface of a Ni single crystal employing three different magnetic imaging techniques and ab initio calcula…
Adhesion and electronic structure of graphene on hexagonal boron nitride substrates
B. Sachs, T. O. Wehling, M. I. Katsnelson +1
We investigate the adsorption of graphene sheets on h-BN substrates by means of first-principles calculations in the framework of adiabatic connection fluctuation-dissipation theor…
