Hall-effect and resistivity measurements in CdTe and ZnTe at high pressure: Electronic structure of impurities in the zincblende phase and the semi-metallic or metallic character of the high-pressure phases
D. Errandonea, A. Segura, D. Martinez-Garcia +1
We carried out high-pressure resistivity and Hall-effect measurements in single crystals of CdTe and ZnTe up to 12 GPa. Slight changes of transport parameters in the zincblende pha…
Experimental and theoretical investigations on ThGeO4 at high pressure
D. Errandonea, Ravhi. S. Kumar, L. Gracia +3
We report here the combined results of angle-dispersive x-ray diffraction experiments performed on ThGeO4 up to 40 GPa and total-energy density-functional theory calculations. Zirc…
Post-spinel transformations and equation of state in ZnGa2O4: Determination at high-pressure by in situ x-ray diffraction
D. Errandonea, Ravhi S. Kumar, F. J. Manjon +2
Room temperature angle-dispersive x-ray diffraction measurements on spinel ZnGa2O4 up to 56 GPa show evidence of two structural phase transformations. At 31.2 GPa, ZnGa2O4 undergoe…
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 x-ray diffraction study on the structure and phase transitions of the defect-stannite ZnGa2Se4 and defect-chalcopyrite CdGa2S4
D. Errandonea, R. S. Kumar, F. J. Manjon +2
X-ray diffraction measurements on the sphalerite-derivatives ZnGa2Se4 and CdGa2S4 have been performed upon compression up to 23 GPa in a diamond-anvil cell. ZnGa2Se4 exhibits a def…
Combined Raman scattering and ab initio investigation of pressure-induced structural phase transitions in the scintillator ZnWO4
D. Errandonea, F. J. Manjon, N. Garro +5
Room-temperature Raman scattering was measured in ZnWO4 up to 45 GPa. We report the pressure dependence of all the Raman-active phonons of the low-pressure wolframite phase. As pre…
