Time-resolved spectral densities of non-thermal electrons in gold
Christopher Seibel, Markus Uehlein, Tobias Held +3
Noble-metal nanoparticles for photocatalysis have become a major research object in recent years due to their plasmon-enhanced strong light-matter interaction. The dynamics of the…
Competing signatures of intersite and interlayer spin transfer in the ultrafast magnetization dynamics
Simon Häuser, Sebastian T. Weber, Christopher Seibel +10
Optically driven intersite and interlayer spin transfer are individually known as the fastest processes for manipulating the spin order of magnetic materials on the sub 100 fs time…
Indirect optical manipulation of the antiferromagnetic order of insulating NiO by ultrafast interfacial energy transfer
Stephan Wust, Christopher Seibel, Hendrik Meer +14
We report the ultrafast, (sub)picosecond reduction of the antiferromagnetic order of the insulating NiO thin film in a Pt/NiO bilayer. This reduction of the antiferromagnetic order…
Impurity states in the magnetic topological insulator V:(Bi,Sb)Te
Thiago R. F. Peixoto, Hendrik Bentmann, Steffen Schreyeck +12
The ferromagnetic topological insulator V:(Bi,Sb)Te has been recently reported as a quantum anomalous Hall (QAH) system. Yet the microscopic origins of the QAH effect and t…
Strong Linear Dichroism in Spin-Polarized Photoemission from Spin-Orbit-Coupled Surface States
Hendrik Bentmann, Henriette Maaß, Eugene E. Krasovskii +5
A comprehensive understanding of spin-polarized photoemission is crucial for accessing the electronic structure of spin-orbit coupled materials. Yet, the impact of the final state…
Quantized electronic fine structure with large anisotropy in ferromagnetic Fe films
C. Seibel, A. Nuber, H. Bentmann +4
We report on the spectroscopic observation of a quantized electronic fine structure near the Fermi energy in thin Fe films grown on W(110). The quantum well states are detected dow…
Single Dirac-cone on the Cs-covered topological insulator surface Sb2Te3(0001)
Christoph Seibel, Henriette Maaß, Minoru Ohtaka +6
Using angle-resolved photoelectron spectroscopy we investigate the surface electronic structure of the three-dimensional topological insulator (TI) Sb2Te3(0001). Our data show the…
Energy distribution and quantum yield for photoemission from air-contaminated gold surfaces under UV illumination close to the threshold
Gerald Hechenblaikner, Tobias Ziegler, Indro Biswas +6
The kinetic energy distributions of photo-electrons emitted from gold surfaces under illumination by UV-light close to the threshold are measured and analyzed. Samples are prepared…
