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…
Electrically and Magnetically Tunable Charge-Density-Wave Transport in Quasi-2D h-BN/1T-TaS2 Thin-Film Heterostructures
Jonas O. Brown, Maedeh Taheri, Nicholas R. Sesing +2
Controlling collective electronic phases in low-dimensional materials is a central challenge for developing technologies based on charge-density waves. Here, we report that perpend…
Quantum Spin Singlet Ground State with Large Excitation Gap in the S = 3/2 quasi-1D van der Waals materials MoX3 (X = I, Br)
Jordan Teeter, Topojit Debnath, Harshil Goyal +18
We report the first experimental evidence for a quantum-disordered spin-singlet ground state and gapped triplon excitations in quasi-one-dimensional van der Waals materials. The in…
Giant Gate Response of the Charge in an Electron-Lattice Condensate
Maedeh Taheri, Jordan Teeter, Topojit Debnath +4
Efficient electrical capacitive control is important for the next generation of ultra-low-power and ultra-fast electronics and energy-storage devices. Correlated electronic phases…
Solution-Processed Inks with Fillers of NbS Quasi-One-Dimensional Charge-Density-Wave Material
Tekwam Geremew, Maedeh Taheri, Nicholas Sesing +4
We report on the solution processing and testing of electronic ink comprised of quasi-one-dimensional NbS charge-density-wave fillers. The ink was prepared by liquid-phase exfo…
