Atomic Ordering in Cubic Bismuth Telluride Alloy Phases at High Pressure
I. Loa, J. -W. G. Bos, R. A. Downie +1
Pressure-induced transitions from ordered intermetallic phases to substitutional alloys to semi-ordered phases were studied in a series of bismuth tellurides. Using angle-dispersiv…
Structural transformations of Li2C2 at high pressures
Ilias Efthimiopoulos, Daryn E. Benson, Sumit Konar +9
Structural changes of Li2C2 under pressure were studied by synchrotron x-ray diffraction in a diamond anvil cell under hydrostatic conditions and by using evolutionary search metho…
Plasmons in Sodium under Pressure: Increasing Departure from Nearly-Free-Electron Behavior
I. Loa, K. Syassen, G. Monaco +3
We have measured plasmon energies in Na under high pressure up to 43 GPa using inelastic x-ray scattering (IXS). The momentum-resolved results show clear deviations, growing with i…
Effect of pressure on the polarized infrared optical response of quasi-one-dimensional LaTiO
S. Frank, C. A. Kuntscher, I. Loa +2
The pressure-induced changes in the optical properties of the quasi-one-dimensional conductor LaTiO were studied by polarization-dependent mid-infrared micro-spectroscopy…
