Control of transport phenomena in magnetic heterostructures by wavelength modulation
Christopher Seibel, Marius Weber, Martin Stiehl +5
We demonstrate the tuneablity of the ultrafast energy flow in magnetic/non-magnetic bilayer structures by changing the wavelength of the optical excitation. This is achieved by an…
Atomic and mesoscopic structure of Dy-based surface alloys on noble metals
Sina Mousavion, Ka Man Yu, Mahalingam Maniraj +4
Surface alloys are a highly tunable class of low dimensional materials with the opportunity to tune and control the spin and charge carrier functionalities on the nanoscale. Here,…
Energy and Momentum Distribution of Surface Plasmon-induced Hot Carriers Isolated via Spatiotemporal Separation
Michael Hartelt, Pavel N. Terekhin, Tobias Eul +6
Understanding the differences between photon-induced and plasmon-induced hot electrons is essential for the construction of devices for plasmonic energy conversion. The mechanism o…
Spectroscopic evidence for a new type of surface resonance at noble metal surfaces
Tobias Eul, Jürgen Braun, Benjamin Stadtmüller +2
We investigate the surface- and bulk-like properties of the pristine (110)-surface of silver using threshold photoemission by excitation with light of 5.9 eV. Using a momentum micr…
Functional meta lenses for compound plasmonic vortex field generation and control
Eva Prinz, Grisha Spektor, Michael Hartelt +3
Surface plasmon polaritons carrying orbital angular momentum are of great fundamental and applied interest. However, common approaches for their generation are restricted to having…
Adsorption-induced modification of the hot electron lifetime in a Pb/Ag111 quantum well system
Florian Haag, Tobias Eul, Lisa Grad +5
The interfacial band structures of multilayer systems play a crucial role for the ultrafast charge and spin carrier dynamics at interfaces. Here, we study the energy- and momentum-…
