Radio-Frequency-Driven Reshaping of the Mesoscale Charge-Density-Wave Landscape in 1T-TaS2 Thin-Film Devices
Maedeh Taheri, Zahra Ebrahim Nataj, Nick Sesing +4
Radio-frequency excitation directly reshapes the mesoscale charge-density-wave landscape in quasi-two-dimensional 1T-TaS2 thin films. Under combined RF and DC bias, the hysteretic…
Phonon Signatures of Near-Room-Temperature Phase Transition in Quasi-One-Dimensional Bi4I4 Topological van der Waals Material
Nidhish Thiruthukkal Puthenveettil, Topojit Debnath, Clayton Mantz +7
The quasi-one-dimensional material Bi4I4 hosts two crystallographically similar polymorphs that realize distinct topological insulating phases separated by a first-order structural…
Anomalous spin-lattice coupling in a 2D antiferromagnetic semiconductor revealed by surface acoustic Rayleigh waves
Zahra Ebrahim Nataj, Md. Sabbir Hossen Bijoy, Vladislav Korostelev +5
Magnetic order in van der Waals magnets can strongly influence their lattice dynamics, yet how this interaction manifests across different phonon length scales remains unclear. Opt…
A Quieter State of Charge -- Ultra-Low-Noise Collective Current in Charge-Density-Wave Nanowires
Subhajit Ghosh, Nicholas Sesing, Tina Salguero +3
Electronic flicker noise limits phase stability in communication systems, reduces the sensitivity and selectivity of sensors, and degrades coherence in quantum devices. There is a…
