PDFgetX3: A rapid and highly automatable program for processing powder diffraction data into total scattering pair distribution functions
Pavol Juhas, Timur Davis, Christopher L. Farrow +1
PDFgetX3 is a new software application for converting X-ray powder diffraction data to atomic pair distribution function (PDF). PDFgetX3 has been designed for ease of use, speed an…
Optical properties of Bi2Te2Se at ambient and high pressure
Ana Akrap, Michael Tran, Alberto Ubaldini +5
The temperature dependence of the complex optical properties of the three-dimensional topological insulator Bi2Te2Se is reported for light polarized in the a-b planes at ambient pr…
Local structure of ReO at ambient pressure from neutron total scattering study
Emil S. Bozin, T. Chatterji, Simon J. L. Billinge
A hypothesis that the local rotations of ReO octahedra persist in the crystallographically untilted ambient phase of ReO is examined by the high-resolution neutron time-of-…
Large magnetothermopower effect in Dirac materials (Sr/Ca)MnBi2
Kefeng Wang, Limin Wang, C. Petrovic
We report temperature and magnetic field dependence of the thermal transport properties in single crystals of (Sr/Ca)MnBi with linear energy dispersion. In SrMnBi thermopow…
Revealing Correlation of Valence State with Nanoporous Structure in Cobalt Catalyst Nanoparticles by in Situ Environmental TEM
Huolin L. Xin, Elzbieta A. Pach, Rosa E. Diaz +3
Simultaneously probing the electronic structure and morphology of materials at the nanometer or atomic scale while a chemical reaction proceeds is significant for understanding the…
Lattice dynamics reveals a local symmetry breaking in the emergent dipole phase of PbTe
Kirsten M. Ø. Jensen, Emil S. Božin, Christos D. Malliakas +5
Local symmetry breaking in complex materials is emerging as an important contributor to materials properties but is inherently difficult to study. Here we follow up an earlier stru…
