Tellurium sublattice instability driven amorphization in the chalcogenide AgSbTe2 under pressure
Baihong Sun, Zihan Zhang, Wei Luo +12
Pressure provides a powerful thermodynamic route to access hidden structural states in functional materials, yet the microscopic origin of pressure-induced amorphization remains el…
Evidence for Many-Body States in NiPS Revealed by Angle-Resolved Photoelectron Spectroscopy
MiÅosz Rybak, Benjamin Pestka, Biplab Bhattacharyya +11
We present -ARPES spectra of the Mott-insulating van der Waals antiferromagnet NiPS. Signatures of strong correlations -- such as the onset of atomic or atomic-ligand multi…
Crystal Anisotropy Implications on the Magneto-Optical Properties of van der Waals FePS3
Ellenor Geraffy, Kusha Sharma, Shahar Zuri +10
Antiferromagnetic FePS3 has recently gained significant interest in its potential applications in spin-related devices. Here, we show that in-plane structural anisotropy has a majo…
Modeling the Thermal Behavior of Photopolymers for In-Space Fabrication
Jonathan Ericson, Daniel Widerker, Eytan Stibbe +15
Future long-duration space missions will require in-situ, on-demand manufacturing of tools and components. Photopolymer-based processes are attractive for this purpose due to their…
Probing the band structure of the strongly correlated antiferromagnet NiPS3 across its phase transition
Benjamin Pestka, Biplab Bhattacharyya, Milosz Rybak +19
NiPS3 is an exfoliable van-der-Waals intralayer antiferromagnet with zigzag-type spin arrangement. It is distinct from other TMPS3 (TM: transition metal) materials by optical excit…
On the ambient conditions crystal structure of AgSbTe2
Baihong Sun, Sergei Grazhdannikov, Muhamed Dawod +6
We present a combined X-ray and neutron diffraction, Raman spectroscopy, and 121Sb NMR studies of AgSbTe2, supported by first-principles calculations aiming to elucidate its crysta…
