Large-Area Deterministic Stamping of 2D Materials on Arbitrarily Patterned Surfaces
Bernardo S. Dias, Reynolds Dziobek-Garrett, Gabriella Mentasti +6
2D materials and their monolayers have attracted widespread interest by virtue of their unique electronic and optical properties. In addition to their remarkable physical character…
CO oxidation by Pt2/Fe3O4: metastable dimer and support configurations facilitate lattice oxygen extraction
Matthias Meier, Jan Hulva, Zdenek Jakub +8
Heterogeneous catalysts based on sub-nanometer metal clusters often exhibit strongly size-dependent properties, and the addition or removal of a single atom can make all the differ…
Electronic and structural properties of crystalline and amorphous (TaNbHfTiZr)C from first principles
Bram van der Linden, Tadeus Hogenelst, Roland Bliem +2
High entropy materials (HEMs) are of great interest for their mechanical, chemical and electronic properties. In this paper we analyse (TaNbHfTiZr)C, a carbide type of HEM, both in…
Ultrathin, sputter-deposited, amorphous alloy films of ruthenium and molybdenum
G. Yetik, A. Troglia, S. Farokhipoor +5
Microscopy and diffraction measurements are presented of ultrathin binary alloy films of ruthenium and molybdenum that are obtained by standard sputter deposition. For compositions…
Unravelling CO adsorption on model single-atom catalysts
Jan Hulva, Matthias Meier, Roland Bliem +6
Understanding how the local environment of a single-atom catalyst affects stability and reactivity remains a significant challenge. We present an in-depth study of Cu1, Ag1, Au1, N…
Subsurface Cation Vacancy Stabilization of the Magnetite (001) Surface
R. Bliem, E. McDermott, P. Ferstl +9
Iron oxides play an increasingly prominent role in heterogeneous catalysis, hydrogen production, spintronics and drug delivery. The surface or material interface can be performance…
Stabilizing Single Ni adatoms on a Two-dimensional Porous Titania Overlayer at the SrTiO(110) Surface
Zhiming Wang, Xianfeng Hao, Stefan Gerhold +7
Nickel vapor-deposited on the SrTiO(110) surface was studied using scanning tunneling microscopy, photoemission spectroscopy (PES), and density functional theory calculations.…
Water Agglomerates on Fe3O4(001)
Matthias Meier, Jan Hulva, Zdenek Jakub +7
Determining the structure of water adsorbed on solid surfaces is a notoriously difficult task, and pushes the limits of experimental and theoretical techniques. Here, we follow the…
An Atomic-Scale View of CO and H2 Oxidation on a Pt-Fe3O4 Model Catalyst
Roland Bliem, Jessi van der Hoeven, Adam Zavodny +6
Metal-support interactions are frequently invoked to explain the enhanced catalytic activity of metal nanoparticles dispersed over reducible metal-oxide supports, yet the atomic sc…
A Multi-Technique Study of Adsorption on Magnetite
Jiri Pavelec, Jan Hulva, Daniel Halwidl +7
The adsorption of on the (001)-( )R45° surface was studied experimentally using temperature programmed desorption (TPD), electron spe…
The role of surface defects in the adsorption of methanol on Fe3O4(001)
Oscar Gamba, Jan Hulva, Jiri Pavelec +4
The adsorption of methanol (CH3OH) at the Fe3O4(001)-c(2x2) surface was studied using X-ray photoelectron spectroscopy (XPS), scanning tunneling microscopy (STM), and temperature-p…
Fe3O4(110)-(1x3) Revisited: Periodic (111) Nano-Facets
Gareth S. Parkinson, Peter Lackner, Oscar Gamba +6
The structure of the Fe3O4(110)-(1x3) surface was studied with scanning tunneling microscopy (STM), low-energy electron diffraction (LEED), and reflection high energy electron diff…
