Identification of the high-pressure phases of alpha-SnWO4 combining x-ray diffraction and crystal structure prediction

Daniel Diaz-Anichtchenko, Jordi Ibáñez, Pablo Botella +7

We have characterized the high-pressure behavior of alpha-SnWO4. The compound has been studied up to 30 GPa using a diamond-anvil cell and synchrotron powder X-ray diffraction. We…

Stability of the tetragonal phase of BaZrO3 under high pressure

Constance Toulouse, Danila Amoroso, Robert Oliva +8

In this paper, we revisit the high-pressure behavior of BaZrO3 by a combination of first-principle calculations, Raman spectroscopy, and x-ray diffraction under high pressure. We c…

Strong substrate strain effects in multilayered WS2 revealed by high-pressure optical measurements

Robert Oliva, Tomasz Woźniak, Paulo E. Faria Junior +5

The optical properties of two-dimensional materials can be effectively tuned by strain induced from a deformable substrate. In the present work we combine first-principles calculat…

Structural and lattice-dynamical properties of Tb2O3 under compression: a comparative study with rare-earth and related sesquioxides

Jordi Ibáñez, Juan Ángel Sans, Vanesa Cuenca-Gotor +9

We report a joint experimental and theoretical investigation of the high-pressure structural and vibrational properties of terbium sesquioxide (Tb2O3). Powder x-ray diffraction and…

Pressure dependence of direct optical transitions in ReS2 and ReSe2

R. Oliva, M. Laurien, F. Dybala +5

We present an experimental and theoretical study of the electronic band structure of ReS2 and ReSe2 at high hydrostatic pressures. The experiments are performed by photoreflectance…
