High-Pressure Monoclinic-Monoclinic Transition in Fergusonite-type HoNbO4
A. B. Garg, D. Errandonea, P. Rodriguez-Hernandez +1
In this paper we perform a high-pressure study of fergusonite-type HoNbO4. Powder x-ray diffraction experiments and ab initio density-functional theory simulations provide evidence…
Pressure-induced phase transition and bandgap collapse in the wide-bandgap semiconductor InTaO4
D. Errandonea, C. Popescu, A. B. Garg +7
A pressure-induced phase transition, associated with an increase of the coordination number of In and Ta, is detected beyond 13 GPa in InTaO4 by combining synchrotron x-ray diffrac…
High-pressure structural and elastic properties of Tl2O3
O. Gomis, D. Santamaria-Perez, J. Ruiz-Fuertes +9
The structural properties of Thallium (III) oxide (Tl2O3) have been studied both experimentally and theoretically under compression at room temperature. X-ray powder diffraction me…
Experimental and theoretical study of structural properties and phase transitions in YAsO4 and YCrO4
D. Errandonea, R. Kumar, J. Lopez-Solano +4
We have performed experimental and theoretical studies of the structural stability of YAsO4 and YCrO4 at high pressures. X-ray diffraction experiments together with ab initio total…
In situ high-pressure synchrotron x-ray diffraction study of CeVO4 and TbVO4 up to 50 GPa
D. Errandonea, R. S. Kumar, S. N. Achary +1
Room temperature angle-dispersive x-ray diffraction measurements on zircon-type TbVO4 and CeVO4 were performed in a diamond-anvil cell up to 50 GPa using neon as pressure-transmitt…
A combined high-pressure experimental and theoretical study of the electronic band-structure of scheelite-type AWO4 (A = Ca, Sr, Ba, Pb) compounds
R. Lacomba-Perales, D. Errandonea, A. Segura +6
The optical-absorption edge of single crystals of CaWO4, SrWO4, BaWO4, and PbWO4 has been measured under high pressure up to ~20 GPa at room temperature. From the measurements we h…
