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…
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…
Topological magnonic properties of an antiferromagnetic chain
Topojit Debnath, Shri Hari Soundararaj, Sohee Kwon +2
The magnonic excitations of a dimerized, one-dimensional, antiferromagnetic chain can be trivial or topological depending on the signs and magnitudes of the alternating exchange co…
Phonon States in NbTe and TaTe Quasi-One-Dimensional van der Waals Crystals
Zahra Ebrahim Nataj, Fariborz Kargar, Sergiy Krylyuk +7
We report the results of polarization-dependent Raman spectroscopy of phonon states in single-crystalline quasi-one-dimensional NbTe and TaTe van der Waals materials. The m…
Specifics of the Elemental Excitations in "True One-Dimensional" MoI van der Waals Nanowires
Fariborz Kargar, Zahra Barani, Nicholas R. Sesing +15
We report on the temperature evolution of the polarization-dependent Raman spectrum of exfoliated MoI, a van der Waals material with a "true one-dimensional" crystal structure…
Metallic vs. Semiconducting Properties of Quasi-One-Dimensional Tantalum Selenide van der Waals Nanoribbons
Fariborz Kargar, Andrey Krayev, Michelle Wurch +7
We conducted a tip-enhanced Raman scattering spectroscopy (TERS) and photoluminescence (PL) study of quasi-1D TaSe3 nanoribbons exfoliated onto gold substrates. At a selenium defic…
Thermal conductivity of the quasi-1D materials TaSe3 and ZrTe3
Topojit Debnath, Bishwajit Debnath, Roger K. Lake
The high breakdown current densities and resilience to scaling of the metallic transition metal trichalcogenides TaSe3 and ZrTe3 make them of interest for possible interconnect app…
Properties of Shape-Engineered Phoxonic Crystals: Brillouin-Mandelstam Spectroscopy and Ellipsometry Study
Chun Yu Tammy Huang, Fariborz Kargar, Topojit Debnath +6
We report the results of Brillouin-Mandelstam spectroscopy and Mueller matrix spectroscopic ellipsometry of the nanoscale "pillar with the hat" periodic silicon structures, reveali…
