Identifying Contact Barrier Types in Few-Layer MoS2 Devices Using Correlative IV, LBIC, and Bias-Dependent KPFM
Ariane Ufer, Zeinab Eftekhari, Benjamin Mayer +4
Electrical contacts between metals and two-dimensional (2D) semiconductors such as molybdenum disulfide (MoS2) critically govern device performance, yet their microscopic nature re…
Magnetically Programmable Surface Acoustic Wave Filters: Device Concept and Predictive Modeling
Michael K. Steinbauer, Peter Flauger, Matthias Küà +7
Filtering surface acoustic wave (SAW) signals of specified frequencies depending on the strength of an external magnetic field in a magnetostrictive material has garnered significa…
Topical review on acousto-optical Floquet engineering of single-photon emitters
Daniel Groll, Daniel Wigger, Matthias Weià +6
The combination of solid state single-photon emitters and mechanical excitations on a common platform is a promising approach for the development of hybrid quantum technologies. In…
Coupling Quantum Dots to Elastic Waves in a Phononic Crystal Waveguide
Jakub RosiÅski, Jakub Rosiński, MichaÅ GaweÅczyk +6
We present a comprehensive study of quantum dot (QD) coupling to various phononic modes in a phononic waveguide, combining multiband kp and configuration-interaction (CI) QD state…
Impact of Electrical Contacts on Transition Metal Dichalcogenides-Based Acoustoelectric and Acousto-Photoelectric Devices
Benjamin Mayer, Felix M. Ehring, Clemens Strobl +4
We study the impact of electrical contact barriers in hybrid WSe-LiNbO-based acoustoelectric and acousto-photoelectric devices using a combination of scanning photocurrent…
Modeling Magnetoelastic Wave Interactions in Magnetic Films and Heterostructures: A finite-difference approach
Peter Flauger, Matthias KüÃ, Michael Karl Steinbauer +8
The (inverse) magnetostrictive effect in ferromagnets couples the magnetic properties to the mechanical stress, allowing for an interaction between the magnetic and mechanical degr…
