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…
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…
Comparative high-pressure structural and electrical transport properties study of thermoelectric (Bi1-xSbx)2Te3 compounds
Chenxin Wei, Dawod Muhamed, Wenting Lu +11
Thermoelectric (Bi1-x Sbx)2Te3 (BST-x) compounds with x=0.2, 0.7 and 0.9 have been studied using synchrotron angle-dispersive powder x-ray diffraction in a diamond anvil cell up to…
High pressure structural and lattice dynamics study of α-InSe
Shiyu Feng, Baihong Sun, Wenting Lu +9
Layered -InSehas been studied using a concomitant in-situ synchrotron angle dispersive powder x-ray diffraction and Raman spectroscopy study in a diamond anvil cell up…
