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…
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…
Anomalous Raman Modes in Tellurides
F. J. Manjón, S. Gallego-Parra, P. Rodríguez-Hernández +4
Two broad bands are usually found in the Raman spectrum of many Te-based chalcogenides, which include binary compounds, like ZnTe, CdTe, HgTe, GaTe, GeTe, SnTe, PbTe, GeTe2, As2Te3…
Experimental and theoretical study of SbPO4 under compression
André Luis de Jesus Pereira, David Santamaría-Pérez, Rosário Vilaplana +14
SbPO4 is a complex monoclinic layered material characterized by a strong activity of the non-bonding lone electron pair (LEP) of Sb. The strong cation LEP leads to the formation of…
