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
Single ion induced surface nanostructures: a comparison between slow highly charged and swift heavy ions
Friedrich Aumayr,Stefan Facsko,A.S. El-Said,A.S. El-Said,A.S. El-Said,Christina Trautmann,Marika Schleberger +6 more
TL;DR: A comparison of surface structures induced by swift heavy ions and slow highly charged ions provides a valuable insight to better understand the formation mechanisms of ion-surface interaction.
Journal ArticleDOI
Ultrafast electronic response of graphene to a strong and localized electric field.
Elisabeth Gruber,Richard A. Wilhelm,Richard A. Wilhelm,Rémi Pétuya,Valerie Smejkal,Roland Kozubek,Anke Hierzenberger,Bernhard C. Bayer,Íñigo Aldazabal,Andrey K. Kazansky,Florian Libisch,Arkady V. Krasheninnikov,Marika Schleberger,Stefan Facsko,Andrei G. Borisov,Andrés Arnau,Andrés Arnau,Friedrich Aumayr +17 more
TL;DR: The ability of freestanding single layer graphene to provide tens of electrons for charge neutralization of a slow highly charged ion within a few femtoseconds is reported on and time-dependent density functional theory is used to gain insight into the multielectron dynamics.
Journal ArticleDOI
Potential sputtering: One contribution of 11 to a Theme 'Sputtering: past, present and future. W. R. Grove 150th Anniversary Issue'.
TL;DR: This work summarizes a series of recent careful experiments in which potential sputtering has been investigated for hyperthermal highly charged ion's impact on various surfaces, presents the different models proposed to explain the possible sputtering phenomenon, and discusses possible applications of potential sputtered for nanostructure fabrication.
Journal ArticleDOI
Emission of electrons from a clean gold surface induced by slow, very highly charged ions at the image charge acceleration limit.
Friedrich Aumayr,Friedrich Aumayr,H. Kurz,H. Kurz,D. H. Schneider,D. H. Schneider,M. A. Briere,M. A. Briere,J. W. Mcdonald,J. W. Mcdonald,C. E. Cunningham,C. E. Cunningham,H. P. Winter,H. P. Winter +13 more
TL;DR: The electron emission yield was found to increase proportionally with the increasing projectile charge state in all cases studied, suggesting no saturation in the ability of the Au target to provide necessary electrons within the above surface interaction time.
