The Anharmonic Origin of the Giant Thermal Expansion of NaBr
Y. Shen, C. N. Saunders, C. M. Bernal +3
All phonons in a single crystal of NaBr were measured by inelastic neutron scattering at temperatures of 10, 300 and 700 K. Even at 300 K the phonons, especially the longitudinal-o…
Entropic elasticity and negative thermal expansion in a simple cubic crystal
David Wendt, Emil Bozin, Joerg Neuefeind +6
While most solids expand when heated, some materials show the opposite behavior: negative thermal expansion (NTE). In polymers and biomolecules, NTE originates from the entropic el…
Anharmonic lattice dynamics of AgO studied by inelastic neutron scattering and first principles molecular dynamics simulations
Tian Lan, Chen W. Li, J. L. Niedziela +4
Inelastic neutron scattering measurements on silver oxide (AgO) with the cuprite structure were performed at temperatures from 40 to 400\,K, and Fourier transform far-infrared…
White Lines and 3d-Occupancy for the 3d Transition-Metal Oxides
J. Graetz, C. C. Ahn, H. Ouyang +2
Electron energy-loss spectrometry was employed to measure the white lines at the L23 absorption edges of the 3d transition-metal oxides and lithium transition-metal oxides. The whi…
