The Unreconstructed α-AlO(0001) Surface is Inhomogeneous and Rough
Johanna I. Hütner-Reisch, Andrea Conti, David Kugler +4
Alumina (AlO) is a key material for thin-film growth and heterogeneous catalysis, where the atomic surface structure critically impacts performance. Using noncontact at…
Multi-Technique Characterization of Rhodium Gem-Dicarbonyls on TiO(110)
Moritz Eder, Faith J. Lewis, Johanna I. Hütner +12
Gem-dicarbonyls of transition metals supported on metal (oxide) surfaces are common intermediates in heterogeneous catalysis. While infrared (IR) spectroscopy is a standard tool fo…
Stoichiometric reconstruction of the AlO(0001) surface
Johanna I. Hütner, Andrea Conti, David Kugler +5
Macroscopic properties of materials stem from fundamental atomic-scale details, yet for insulators, resolving surface structures remains a challenge. The basal (0001) plane of -…
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…
Oxygen-Terminated (1x1) Reconstruction of Reduced Magnetite FeO(111)
Florian Kraushofer, Matthias Meier, Zdeněk Jakub +7
The (111) facet of magnetite (FeO) has been studied extensively by experimental and theoretical methods, but controversy remains regarding the structure of its low-energy s…
Atomically smooth films of CsSb: a chemically robust visible light photocathode
C. T. Parzyck, C. A. Pennington, W. J. I. DeBenedetti +14
Alkali antimonide semiconductor photocathodes provide a promising platform for the generation of high brightness electron beams, which are necessary for the development of cutting-…
Rapid oxygen exchange between hematite and water vapor
Zdenek Jakub, Matthias Meier, Florian Kraushofer +6
Oxygen exchange at oxide/liquid and oxide/gas interfaces is important in technology and environmental studies, as it is closely linked to both catalytic activity and material degra…
A single-crystal alkali antimonide photocathode: high efficiency in the ultra-thin limit
C. T. Parzyck, A. Galdi, J. K. Nangoi +10
The properties of photoemission electron sources determine the ultimate performance of a wide class of electron accelerators and photon detectors. To date, all high-efficiency visi…
Atomic-scale studies of Fe3O4(001) and TiO2(110) surfaces following immersion in CO2-acidified water
Francesca Mirabella, Jan Balajka1, Jiri Pavelec +5
Difficulties associated with the integration of liquids into a UHV environment make surface-science style studies of mineral dissolution particularly challenging. Recently, we deve…
Self-limited Growth of an Oxyhydroxide Phase at the Fe3O4(001) Surface in Liquid and Ambient Pressure Water
Florian Kraushofer, Francesca Mirabella, Jian Xu +10
Atomic-scale investigations of metal oxide surfaces exposed to aqueous environments are vital to understand degradation phenomena (e.g. dissolution and corrosion) as well as the pe…
Apparatus for dosing liquid water in ultrahigh vacuum
Jan Balajka, Jiri Pavelec, Mojmir Komora +2
The structure of the solid-liquid interface often defines function and performance of materials in applications. To study the interface at the atomic scale, we extended an ultrahig…
