Ge-based Clinopyroxene series: first principles and experimental local probe study
Ricardo P. Moreira, E. Lora da Silva, Gonçalo N. P. Oliveira +9
The structural and electronic properties of the CaMnGeO and SrMnGeO clinopyroxene systems have been investigated by means of perturbed angular correlation (PAC) mea…
Pressure-Induced Phase Transformations of Quasi-2D SrHfO
M. C. B. Barbosa, E. Lora da Silva, P. Neenu Lekshmi +5
We present an \textit{ab-initio} study of the quasi-2D layered perovskite SrHfO com\-pound, performed within the framework of the Density Functional Theory and lattice…
Layered topological semimetal GaGeTe: new polytype with non-centrosymmetric structure
S. Gallego-Parra, E. Bandiello, A. Liang +8
GaGeTe is a layered material composed of germanene and GaTe sublayers that has been recently predicted to be a basic Z2 topological semimetal. To date, only one polytype of GaGeTe…
Theoretical study of the stability of the tetradymite-like phases of SbS, BiS, and SbSe
E. Lora da Silva, J. M. Skelton, P. Rodríguez-Hernández +5
We report a comparative theoretical study of the \textit{Pnma} and \textit{R-3m} phases of SbS, BiS, and SbSe close to ambient pressure. Our enthalpy calcul…
-AsTe: Pressure-Induced 3D Dirac Semi-Metal
E. Lora da Silva, A. Leonardo, Tao Yang +5
We report a theoretical \textit{ab-initio} study of -AsTe ( symmetry) at hydrostatic pressures up to 12 GPa. We have systematically characterized the vibratio…
