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…

D-Wave Phonon Angular Momentum Texture in Altermagnets by Magnon-Phonon Hybridization

Hannah Bendin, Alexander Mook, Ingrid Mertig +1

In altermagnets, the magnon bands are anisotropically spin-split in reciprocal space without relativistic or dipolar spin-spin interactions. In this work, we theoretically study ma…

Spin filtering on demand via localized states in an atomic-scale resonant tunneling magnetic tunnel junction

Maciej Bazarnik, Anika Schlenhoff

Spin filtering and its back-action spin transfer torque (STT) are key ingredients of latest spintronic devices based on magnetic tunnel junctions (MTJs). Resonant tunneling (RT), i…

Topological Magnon-Plasmon Hybrids

Tomoki Hirosawa, Pieter M. Gunnink, Alexander Mook

We study magnon-plasmon coupling in effectively two-dimensional stacks of van der Waals layers in the context of the band structure topology. Invoking the quasiparticle approximati…
