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…
Exploring Nanoscale Photoresponse Mechanisms for Enhanced Photothermoelectric Effects in van der Waals Interfaces
Da Xu, Qiushi Liu, Boqun Liang +7
Integrated photodetectors are crucial for their high speed, sensitivity, and efficient power consumption. In these devices, photocurrent generation is primarily attributed to the p…
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…
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…
Spin - Phonon Coupling in Nickel Oxide Determined from Ultraviolet Raman Spectroscopy
E. Aytan, B. Debnath, F. Kargar +6
Nickel oxide (NiO) has been studied extensively for various applications ranging from electrochemistry to solar cells [1,2]. In recent years, NiO attracted much attention as an ant…
Inelastic Light Scattering Spectroscopy of Magnons and Phonons in Nickel Oxide: Effects of Temperature
M. M. Lacerda, F. Kargar, E. Aytan +7
We report results of an investigation of the temperature dependence of the magnon and phonon frequencies in NiO. A combination of Brillouin - Mandelstam and Raman spectroscopies al…
