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…
High-pressure structural and lattice-dynamics study of Yttria-Stabilized Zirconia
Shennan Hu, Baihong Sun, Wenting Lu +9
The structural evolution of two selected compositions of Yttria-Stabilized Zirconia (YSZ), with 3mol% (3YSZ) and 8mol% (8YSZ) of Y2O3, have been investigated under pressure using i…
2D MoS/Au interfaces for enhanced opto-electronic response with sub-bandgap photons
Jinlei Wu, Wei Huang, Ahsan Ali +5
Monolayer MoS is a direct band gap semiconductor with potential applications in optoelectronics and photonics. MoS also has a large optical nonlinearity. However, the atomi…
High pressure lattice dynamics study of few layer--InSe
Shiyu Feng, Anurag Ghosh, Gautham Vijayan +4
Few-layer -InSe has been studied under pressure using Raman spectroscopy in a diamond anvil cell up to 60 GPa (at room temperature). A combination of AFM and Raman was…
High pressure synthesis and structural study of AuGa2 intermetallic compound
Azkar Saeed Ahmad, Zhuoyang Yu, Sizhe Wang +8
We report the synthesis of the AuGa2 intermetallic compound, using a direct reaction of the relevant elements at room temperature and at very low pressure. The pressure needed to s…
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…
