Real-time exciton dynamics in two-dimensional materials under ultrashort laser pulses
Dmitry Tumakov, Daria Popova-Gorelova
The optical response of two-dimensional materials is often significantly impacted by excitonic effects due to the reduced screening of attractive Coulomb interactions in low-dimens…
Laser-dressed partial density of states
Tatiana Bezriadina, Daria Popova-Gorelova
The manipulation of material properties by laser light holds great promise for the development of future technologies. However, the full picture of the electronic response to laser…
Rubidium intercalation in epitaxial monolayer graphene
Letizia Ferbel, Stefano Veronesi, Tevfik Onur Mentes +7
Alkali metal intercalation of graphene layers has been of particular interest due to potential applications in electronics, energy storage, and catalysis. Rubidium (Rb) is one of t…
Revealing fingerprints of valence excitons in x-ray absorption spectra with the Bethe-Salpeter equation
Nasrin Farahani, Daria Popova-Gorelova
The Bethe-Salpeter equation (BSE) is a powerful theoretical approach that is capable to accurately treat electron-hole interactions in materials in an excited state. We developed a…
Femtosecond concerted rotation of molecules on a 2D material interface
Kiana Baumgärtner, Misa Nozaki, Marvin Reuner +20
Interfaces between molecules and 2D materials exhibit energy-driven functionalities, wherein charge transfer directs molecular motion. Unlike equilibrium systems, where molecular a…
Interpretation of micromorphic constitutive relations for porous materials at the microscale via harmonic decomposition
Geralf Hütter
Micromorphic theories became an established tool to model size effects in materials like dispersion, localization phenomena or (apparently) size dependent properties. However, the…
Massively strained VO2 thin film growth on RuO2
Simon Fischer, Jon-Olaf Krisponeit, Michael Foerster +3
Strain engineering vanadium dioxide thin films is one way to alter this material's characteristic first order transition from semiconductor to metal. In this study we extend the ex…
Integration of external electric fields in molecular dynamics simulation models for resistive switching devices
Tobias Gergs, Sven Dirkmann, Thomas Mussenbrock
Resistive switching devices emerged a huge amount of interest as promising candidates for non-volatile memories as well as artificial synapses due to their memristive behavior. The…
In depth nano spectroscopic analysis on homogeneously switching double barrier memristive devices
Julian Strobel, Mirko Hansen, Sven Dirkmann +10
Memristors based on a double barrier design have been analysed by various nano spectroscopic methods to unveil details about its microstructure and conduction mechanism. The device…
Resistive Switching in Memristive Electrochemical Metallization Devices
Sven Dirkmann, Thomas Mussenbrock
We report on resistive switching of memristive electrochemical metallization devices using 3D kinetic Monte Carlo simulations describing the transport of ions through a solid state…
Direct growth of low-doped graphene on Ge/Si(001) surfaces
J. Dabrowski, G. Lippert, J. Avila +12
The practical difficulties to use graphene in microelectronics and optoelectronics is that the available methods to grow graphene are not easily integrated in the mainstream techno…
Morphology and chemical composition of cobalt germanide islands on Ge(001): in-situ nanoscale insights into contact formation for Ge-based device technology
M. Ewert, Th. Schmidt, J. I. Flege +7
The reactive growth of cobalt germanide on Ge(001) was investigated by means of in-situ x-ray absorption spectroscopy photoemission electron microscopy (XAS-PEEM), micro-illuminati…
Nanosized superparamagnetic precipitates in cobalt-doped ZnO
Matthias Opel, Karl-Wilhelm Nielsen, Sebastian Bauer +6
The existence of semiconductors exhibiting long-range ferromagnetic ordering at room temperature still is controversial. One particularly important issue is the presence of seconda…
