Interactions of nanoparticles and surfaces (2008)
Die Forschung beschäftigt sich seit Jahrhunderten [deG97] mit dem Problem, unterschiedliche Materialien aufeinander zu kleben. Erst kürzlich wurden Methoden entwickelt, mit denen die...
Taubert, Richard, Hudert, Florian, Bartels, Albrecht, Merkt, Florian, Habenicht, Anja, Leiderer, Paul, ...
We investigate the impulsively excited acoustic dynamics of nanoscale Au triangles of different sizes and thicknesses on silicon and glass substrates. We employ high-speed asynchronous optical...
Acoustic laser cleaning of silicon surfaces (2007)
Geldhaser, Tobias, Ziese, Florian, Merkt, Florian, Erbe, Artur, Boneberg, Johannes, Leiderer, Paul
We investigate the detachment of small particles from silicon surfaces by means of acoustic waves generated by laser-induced plasma formation at the back side of the sample. It is demonstrated that...
Capped colloids as light-mills in optical traps (2006)
Merkt, Florian, Erbe, Artur, Leiderer, Paul
Custom-designed colloidal particles in optical tweezers act as lightmills in a fluid. In particular, aqueous suspensions of capped silica colloids, in which half of the surface is covered with metal...
