Defect Structure of the High-Dielectric-Constant Perovskite Cacu3ti4o12
L. Wu, Y. Zhu, S. Park +3
Using transmission electron microscopy (TEM) we studied CaCu3Ti4O12, an intriguing material that exhibits a huge dielectric response, up to kilohertz frequencies, over a wide range…
Microscopic Surface Structure of Liquid Alkali Metals
Holger Tostmann, Elaine DiMasi, Oleg G. Shpyrko +3
We report an x-ray scattering study of the microscopic structure of the surface of a liquid alkali metal. The bulk liquid structure factor of the eutectic K67Na33 alloy is characte…
Structural phase transformation and phase boundary/stability studies of field-cooled Pb(Mg1/3Nb2/3O3)-32%PbTiO3 crystals
Hu Cao, Feiming Bai, Jiefang Li +4
Structural phase transformations in (001)-oriented (1-x)Pb(Mg1/3Nb2/3O3)-32%PbTiO3 (PMN-x%PT) crystals have been investigated by x-ray diffraction. A C->T->MC sequence was observed…
Tunable Thermal Expansion Behavior in the Intermetallic YbGaGe
F. R. Drymiotis, Y. Lee, G. Lawes +6
We investigate the effects of carbon and boron doping on the thermal expansion in the hexagonal (P63/mmc) intermetallic YbGaGe. X-ray powder diffraction was used to measure the lat…
Large crystal local-field effects in the dynamical structure factor of rutile TiO2
I. G. Gurtubay, Wei Ku, J. M. Pitarke +4
We present ab initio time-dependent-density-functional calculations and non-resonant inelastic x-ray scattering measurements of the dynamical structure factor of rutile TiO2. Our c…
Low-temperature phases in Pb(Zr0.52Ti0.48)O3: A neutron powder diffraction study
D. E. Cox, B. Noheda, G. Shirane
A neutron powder diffraction study has been carried out on Pb(Zr0.52Ti0.48)O3 in order to resolve an ongoing controversy about the nature of the low-temperature structure of this s…
