Biaxial Strain Control of Helimagnetism via Chemical Expansion in Thin Film SrFeO3
Jennifer Fowlie, Jiarui Li, Danilo Puggioni +15
We demonstrate control of helimagnetic order in biaxially strained SrFeO3 thin films using neutron diffraction and resonant soft x-ray scattering. SrFeO3, a negative charge-transfe…
Selecting "Convenient Observers" to Probe the Atomic Structure of Epitaxial Graphene Grown on Ir(111) via Photoelectron Diffraction
Lucas Barreto, Luis Henrique de Lima, Daniel Coutinho Martins +4
Epitaxial graphene grown on metallic substrates presents, in several cases, a long-range periodic structure due to a lattice mismatch between the graphene and the substrate. For in…
Non-magnetic ground state of Ni adatoms on Te-terminated bismuth chalcogenide topological insulators
M. Vondracek, J. Honolka, L. Cornils +20
We report on the quenching of single Ni adatom moments on Te-terminated Bi2Te2Se and Bi2Te3 topological insulator surfaces. The effect becomes manifested as a missing X-ray magneti…
Surface Structure Determination of Black Phosphorus Using Photoelectron Diffraction
Luis Henrique de Lima, Lucas Barreto, Richard Landers +1
Atomic structure of single-crystalline black phosphorus was studied by high resolution synchrotron-based photoelectron diffraction (XPD). The results show that the topmost phosphor…
High Crystallinity and Decoupling of Graphene on a Metal: Reduced Coulomb Screening and Tunable pn-Junctions
Søren Ulstrup, Mie Andersen, Marco Bianchi +4
High quality epitaxial graphene films can be applied as templates for tailoring graphene-substrate interfaces that allow for precise control of the charge carrier behavior in graph…
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…
Tailoring the electronic texture of a topological insulator via its surface orientation
Lucas Barreto, Wendell Simoes e Silva, Malthe Stensgaard +5
Three dimensional topological insulator crystals consist of an insulating bulk enclosed by metallic surfaces, and detailed theoretical predictions about the surface state band topo…
Detecting the local transport properties and the dimensionality of transport of epitaxial graphene by a multi-point probe approach
Lucas Barreto, Edward Perkins, Jens Johannsen +5
The electronic transport properties of epitaxial monolayer graphene (MLG) and hydrogen-intercalated quasi free-standing bilayer graphene (QFBLG) on SiC(0001) are investigated by mi…
Transfer-free electrical insulation of epitaxial graphene from its metal substrate
Silvano Lizzit, Rosanna Larciprete, Paolo Lacovig +8
High-quality, large-area epitaxial graphene can be grown on metal surfaces but its transport properties cannot be exploited because the electrical conduction is dominated by the su…
