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…
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…
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…
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…
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…
