Water adsorption on a model silicate surface: wollastonite (100)
Luca Lezuo, Andrea Conti, Alexander Hoheneder +7
Water adsorption on silicate surfaces is a critical yet poorly understood process relevant to, e.g., mineral weathering and cement hydration. This study investigates the structure…
Total Variation-Based Image Decomposition and Denoising for Microscopy Images
Marco Corrias, Giada Franceschi, Michele Riva +5
Experimentally acquired microscopy images are unavoidably affected by the presence of noise and other unwanted signals, which degrade their quality and might hide relevant features…
ViPErLEED package I: Calculation of curves and structural optimization
Florian Kraushofer, Alexander M. Imre, Giada Franceschi +6
Low-energy electron diffraction (LEED) is a widely used technique in surface-science. Yet, it is rarely used to its full potential. The quantitative information about the surface s…
Digging its own Site: Linear Coordination Stabilizes a Pt1/Fe2O3 Single-Atom Catalyst
Ali Rafsanjani-Abbasi, Florian Buchner, Faith J. Lewis +15
Determining the local coordination of the active site is a pre-requisite for the reliable modeling of single-atom catalysts (SACs). Obtaining such information is difficult on powde…
NH adsorption and competition with HO on a hydroxylated aluminosilicate surface
Giada Franceschi, Andrea Conti, Luca Lezuo +4
The interaction between ammonia (NH) and (alumino)silicates is of fundamental and applied importance, yet the specifics of NH adsorption on silicate surfaces remain largely…
Wave-function engineering on superconducting substrates: Chiral Yu-Shiba-Rusinov molecules
Lisa M. Rütten, Harald Schmid, Eva Liebhaber +6
Magnetic adatoms on superconductors give rise to Yu-Shiba-Rusinov (YSR) states that hold considerable interest for the design of topological superconductivity. Here, we show that Y…
Evolution of the surface atomic structure of multielement oxide films: curse or blessing?
Giada Franceschi, Renè Heller, Michael Schmid +2
Atomically resolved scanning tunneling microscopy (STM) and x-ray photoelectron spectroscopy (XPS) are used to gain atomic-scale insights into the heteroepitaxy of lanthanum-stront…
How water binds to microcline feldspar (001)
Giada Franceschi, Andrea Conti, Luca Lezuo +4
Microcline feldspar (KAlSiO) is a common mineral with important roles for Earth's ecological balance. It participates in the carbon, potassium, and water cycles, contributi…
Interaction of surface cations of cleaved mica with water in vapor and liquid forms
Giada Franceschi, Sebastian Brandstetter, Jan Balajka +5
Natural minerals contain ions that become hydrated when they come into contact with water in vapor and liquid forms. Muscovite mica -- a common phyllosilicate with perfect cleavage…
Resolving the intrinsic short-range ordering of K ions on cleaved muscovite mica
Giada Franceschi, Pavel Kocán, Andrea Conti +8
Muscovite mica, KAl(SiAl)O(OH), is a common layered phyllosilicate with perfect cleavage planes. The atomically flat surfaces obtained through cleaving lend them…
Reconstruction changes drive surface diffusion and determine the flatness of oxide surfaces
Giada Franceschi, Michael Schmid, Ulrike Diebold +1
Surface diffusion on metal oxides is key in many areas of materials technology, yet it has been scarcely explored at the atomic scale. This work provides phenomenological insights…
The effect of different InO(111) surface terminations on CO adsorption
Sabrina M. Gericke, Minttu M. Kauppinen, Margareta Wagner +15
InO-based catalysts have shown high activity and selectivity for CO hydrogenation to methanol, however the origin of the high performance of InO is still unclea…
Water Structures Reveal Local Hydrophobicity on the In2O3(111) Surface
Hao Chen, Matthias A. Blatnik, Christian L. Ritterhoff +9
Clean oxide surfaces are generally hydrophilic. Water molecules anchor at undercoordinated surface metal atoms that act as Lewis-acid sites, and they are stabilized by H bonds to u…
Real-space investigation of polarons in hematite Fe2O3
Jesus Redondo, Michele Reticcioli, Vit Gabriel +17
In polarizable materials, electronic charge carriers interact with the surrounding ions, leading to quasiparticle behaviour. The resulting polarons play a central role in many mate…
Hematite in top and side view: resolving long-standing controversies about its surface structure
Jesús Redondo, Jan Michalička, Giada Franceschi +13
Hematite is the most-investigated iron oxide model system in photo and electrocatalytic research. The rich chemistry of Fe and O allows for many bulk and surf…
Tuning a two-impurity Kondo system by a moiré superstructure
Sergey Trishin, Christian Lotze, Friedemann Lohss +4
Two-impurity Kondo models are paradigmatic for correlated spin-fermion systems. Working with Mn atoms on Au(111) covered by a monolayer of MoS, we tune the inter-adatom exchang…
Single Rh adatoms stabilized on α-Fe2O3(1-102) by co-adsorbed water
Florian Kraushofer, Lena Haager, Moritz Eder +8
Oxide-supported single-atom catalysts are commonly modelled as a metal atom substituting surface cation sites in a low-index surface. Adatoms with dangling bonds will inevitably co…
Surface Reduction State Determines Stabilization and Incorporation of Rh on α-Fe2O3(1-102)
Florian Kraushofer, Nikolaus Resch, Moritz Eder +9
Iron oxides (FeOx) are among the most common support materials utilized in single atom catalysis. The support is nominally Fe2O3, but strongly reductive treatments are usually appl…
Does a pristine, unreconstructed SrTiO(001) surface exist?
Igor Sokolović, Giada Franceschi, Zhichang Wang +6
The surfaces of perovskite oxides affect their functional properties, and while a bulk-truncated (11) termination is generally assumed, its existence and stability is contr…
2D Surface Phase Diagram of a Multicomponent Perovskite Oxide: LaSrMnO(110)
Giada Franceschi, Michael Schmid, Ulrike Diebold +1
The many surface reconstructions of (110)-oriented lanthanum--strontium manganite (LaSrMnO, LSMO) were followed as a function of the oxygen chemical potential (…
