Temperature dependence of the Raman spectrum of orthorhombic Bi2Se3
Irene Mediavilla-Martinez, Christian Kramberger, Shabnam Dadgostar +9
Bismuth selenide, a benchmark topological insulator, grows in a trigonal structure at ambient conditions and exhibits a number of enticing properties related to the formation of Di…
Accurate Determination of the Band-Gap Energy of the Rare-Earth Niobate Series
Alka B. Garg, David Vie, Placida Rodriguez-Hernandez +3
In this work, we report diffuse reflectivity measurements in InNbO4, ScNbO4, YNbO4, and eight different rare-earth niobates. From a comparison with the established values of the ba…
Structural and vibrational study of Zn(IO3)2 combining high-pressure experiments and density-functional theory
A. Liang, C. Popescu, F. J. Manjon +4
We report a characterization of the high-pressure behavior of zinc-iodate, Zn(IO3)2. By the combination of x-ray diffraction, Raman spectroscopy, and first-principles calculations…
Structural, Vibrational, and Electronic Behavior of Two GaGeTe Polymorphs under compression
Enrico Bandiello, Samuel Gallego-Parra, Akun Liang +14
GaGeTe is a layered topological semimetal that has been recently found to exist in at least two different polytypes, -GaGeTe () and -GaGeTe (). Here we re…
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…
