Journal ArticleDOI
Intrinsic defects on a TiO2(110)(1×1) surface and their reaction with oxygen: a scanning tunneling microscopy study
Ulrike Diebold,Jeremiah Lehman,Talib Mahmoud,Markus Kuhn,G. Leonardelli,W. Hebenstreit,Michael Schmid,Peter Varga +7 more
TL;DR: In this article, a scanning tunneling microscopy (STM) study of the rutile TiO2(110) surface was performed, and the surface was prepared by sputtering and annealing in an ultrahigh vacuum (UHV).
Journal ArticleDOI
Structure of the ultrathin aluminum oxide film on NiAl(110).
Georg Kresse,Georg Kresse,Michael Schmid,Michael Schmid,E. Napetschnig,E. Napetschnig,Maxim Shishkin,Maxim Shishkin,Lukas Köhler,Lukas Köhler,Peter Varga,Peter Varga +11 more
TL;DR: It is proposed that the same building blocks can be found on the surfaces of bulk oxides, such as the reduced corundum (0001) surface, which is a wide-gap insulator.
Journal ArticleDOI
Interaction of slow multicharged ions with solid surfaces
Andrés Arnau,Friedrich Aumayr,Pedro M. Echenique,M. Grether,W. Heiland,J. Limburg,R.W.H. Morgenstern,Philippe Roncin,Stefan Schippers,R. Schuch,Nikolaus Stolterfoht,Peter Varga,Theo J. M. Zouros,Hannspeter Winter +13 more
TL;DR: In this paper, the main aspects of the interaction of slow (impact velocity typically below 1 a.u.) multicharged ions (MCI) with atomically clean solid surfaces of metals, semiconductors and insulators are discussed.
Journal ArticleDOI
Two-dimensional oxide on Pd(111).
Edvin Lundgren,Georg Kresse,C Klein,Mattias Borg,Jesper N Andersen,M. De Santis,Y. Gauthier,C. Konvicka,Michael Schmid,Peter Varga +9 more
TL;DR: This study demonstrates how the atomic arrangement of a nontrivial incommensurate surface can be solved by molecular dynamics in a case where experimental techniques alone give no solution.
Journal ArticleDOI
Self-limited growth of a thin oxide layer on Rh(111).
Johan Gustafson,Anders Mikkelsen,Mattias Borg,Edvin Lundgren,L Kohler,Georg Kresse,Michael Schmid,Peter Varga,Junji Yuhara,Xavier Torrelles,C Quiros,Jesper N Andersen +11 more
TL;DR: The oxidation of the Rh(111) surface at oxygen pressures from 10(-10) mbar to 0.5 bar and temperatures between 300 and 900 K produces a trilayer O-Rh-O surface oxide which, although not thermodynamically stable, prevents further oxidation at intermediate pressures.
