Theoretical study of phase transitions in Sb2S3, Bi2S3 and Sb2Se3 under compression
E. Lora da Silva, J. M. Skelton, P. Rodríguez-Hernández +3
We report a theoretical study of Sb2S3, Sb2Se3 and Bi2S3 sesquichalcogenides at hydrostatic pressures up to 60 GPa. We explore the possibility that the R-3m, C2/m, C2/c and Im-3m p…
Structural study of alfa-Bi2O3 under pressure
A. L. J. Pereira, D. Errandonea, A. Beltrán +8
An experimental and theoretical study of the structural properties of monoclinic bismuth oxide (alfa-Bi2O3) under high pressures is here reported. Both synthetic and mineral bismit…
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…
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…
Electronic and phononic properties of the chalcopyrite CuGaS2
A. H. Romero, M. Cardona, R. K. Kremer +5
The availability of ab initio electronic calculations and the concomitant techniques for deriving the corresponding lattice dynamics have been profusely used for calculating thermo…
High-pressure structural phase transitions in CuWO4
J. Ruiz-Fuertes, D. Errandonea, R. Lacomba-Perales +9
We study the effects of pressure on the structural, vibrational, and magnetic behavior of cuproscheelite. We performed powder x-ray diffraction and Raman spectroscopy experiments u…
High-pressure phase transitions and compressibility of wolframite-type tungstates
J. Ruiz-Fuertes, S. Lopez-Moreno, D. Errandonea +7
This paper reports an investigation on the phase diagram and compressibility of wolframite-type tungstates by means of x-ray powder diffraction and absorption in a diamond-anvil ce…
Electronic, vibrational, and thermodynamic properties of ZnS (zincblende and rocksalt structure)
M. Cardona, R. K. Kremer, R. Lauck +4
We have measured the specific heat of zincblende ZnS for several isotopic compositions and over a broad temperature range (3 to 1100 K). We have compared these results with calcula…
Determination of the high-pressure crystal structure of BaWO4 and PbWO4
D. Errandonea, J. Pellicer-Porres, F. J. Manjon +10
We report the results of both angle-dispersive x-ray diffraction and x-ray absorption near-edge structure studies in BaWO4 and PbWO4 at pressures of up to 56 GPa and 24 GPa, respec…
High-pressure structural study of the scheelite tungstates CaWO4 and SrWO4
D. Errandonea, J. Pellicer-Porres, F. J. Manjon +10
Angle-dispersive x-ray diffraction (ADXRD) and x-ray absorption near edge structure (XANES) measurements have been performed in the AWO4 tungstates CaWO4 and SrWO4 under high press…
