X-ray studies of phonon softening in tise2.

چکیده
The charge-density-wave transition in TiSe (2), which results in a commensurate (2x2x2) superlattice at temperatures below approximately 200 K, presumably involves softening of a zone-boundary phonon mode. For the first time, this phonon-softening behavior has been examined over a wide temperature range by synchrotron x-ray thermal diffuse scattering.

متن کاملDYNAMICS OF FERROELECTRIC NANO CLUSTER IN BaTiO3 OBSERVED AS A REAL TIME CORRELATION BETWEEN TWO SOFT X-RAY LASER PULSES
We carry out a theoretical investigation to clarify the dynamic property of photo-created nano-sized ferroelectric cluster observed in the paraelectric BaTiO3 as a real time correlation of speckle pattern between two soft X-ray laser pulses, at just above the paraelectricferroelectric phase transition temperature. Based on a model with coupled soft X-ray photon and ferroelectric phonon mode, we...
متن کاملPhonon anomalies in a-uranium
The temperature dependence of the phonon spectra of a-uranium has recently been measured by inelastic neutron scattering and inelastic X-ray scattering. Although there is little evidence of any anharmonicity, the phonon shows some softening in the optic modes at the zone boundary. Furthermore, an extra mode forms at high temperatures, which is incompatible with a structure composed of a monocli...
متن کاملSuperconductivity at 2.3 K in the misfit compound (PbSe)1.16(TiSe2)2
The structural misfit compound PbSe 1.16 TiSe2 2 is reported. It is a superconductor with a Tc of 2.3 K. PbSe 1.16 TiSe2 2 derives from a parent compound, TiSe2, which shows a charge-density wave transition and no superconductivity. The crystal structure, characterized by high-resolution electron microscopy and powder x-ray diffraction, consists of two layers of 1T-TiSe2 alternating with a doub...
