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…
Hydrostatic pressure response of an oxide two-dimensional electron system
J. Zabaleta, V. S. Borisov, R. Wanke +10
Two-dimensional electron systems with fascinating properties exist in multilayers of standard semiconductors, on helium surfaces, and in oxides. Compared to the two-dimensional (2D…
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…
Pressure-induced phase transition and superconductivity in YBa2Cu4O8
S. M. Souliou, A. Subedi, Y. T. Song +4
We investigate the pressure and temperature dependence of the lattice dynamics of the underdoped, stoichiometric, high temperature superconductor YBa2Cu4O8 by means of Raman spectr…
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…
Superconductivity in SnO: a Nonmagnetic Analog to Fe-based Superconductors?
M. K. Forthaus, K. Sengupta, O. Heyer +6
We found that under pressure SnO with alpha-PbO structure, the same structure as in many Fe-based superconductors, e.g. beta-FeSe, undergoes a transition to a superconducting state…
