Observation of multi-directional energy transfer in a hybrid plasmonic-excitonic nanostructure
Tommaso Pincelli, Thomas Vasileiadis, Shuo Dong +15
Hybrid plasmonic devices involve a nanostructured metal supporting localized surface plasmons to amplify light-matter interaction, and a non-plasmonic material to functionalize cha…
Nuclear dynamics of singlet exciton fission: a direct observation in pentacene single crystals
Hélène Seiler, Marcin Krynski, Daniela Zahn +7
Singlet exciton fission (SEF) is a key process in the development of efficient opto-electronic devices. An aspect that is rarely probed directly, and yet has a tremendous impact on…
Lattice dynamics and ultrafast energy flow between electrons, spins, and phonons in a 3d ferromagnet
Daniela Zahn, Florian Jakobs, Yoav William Windsor +8
The ultrafast dynamics of magnetic order in a ferromagnet are governed by the interplay between electronic, magnetic and lattice degrees of freedom. In order to obtain a microscopi…
Anisotropic Nonequilibrium Lattice Dynamics of Black Phosphorus
Daniela Zahn, Patrick-Nigel Hildebrandt, Thomas Vasileiadis +4
Black phosphorus has recently attracted significant attention for its highly anisotropic properties. A variety of ultrafast optical spectroscopies has been applied to probe the car…
Ultrafast heat flow in heterostructures of Au nanoclusters on thin-films: atomic-disorder induced by hot electrons
Thomas Vasileiadis, Lutz Waldecker, Dawn Foster +5
We study the ultrafast structural dynamics, in response to electronic excitations, in heterostructures composed of Au nanoclusters on thin-film substrates with the use of f…
