Electron emission from a metal nano-tip by ultrashort laser pulses
G Wachter, C Lemell, J Burgdörfer
We theoretically investigate the interaction of near-infrared few cycle laser pulses of moderate intensity with nano-scale metal tips. Macroscopic field enhancement leads to cohere…
Modelling surface restructuring by slow highly charged ions
G. Wachter, K. Tökési, G. Betz +2
We theoretically investigate surface modifications on alkaline earth halides due to highly charged ion impact, focusing on recent experimental evidence for both etch pit and nano-h…
Geometrical model fitting for interferometric data: GEM-FIND
D. Klotz, S. Sacuto, C. Paladini +2
We developed the tool GEM-FIND that allows to constrain the morphology and brightness distribution of objects. The software fits geometrical models to spectrally dispersed interfer…
Phase diagram for nanostructuring CaF surfaces by slow highly charged ions
A. S. El-Said, R. A. Wilhelm, R. Heller +6
Impacts of individual slow highly charged ions on alkaline earth halide and alkali halide surfaces create nano-scale surface modifications. For different materials and impact energ…
Electron rescattering at metal nanotips induced by ultrashort laser pulses
Georg Wachter, Christoph Lemell, Joachim Burgdörfer +3
We report on the first investigation of plateau and cut-off structures in photoelectron spectra from nano-scale metal tips interacting with few-cycle near-infrared laser pulses. Th…
