X-ray thermal diffuse scattering and its studies of lattice dynamics
X-ray scattering by lattice thermal vibrations give rise to thermal diffuse scattering (TDS). TDS contain valuable information about lattice dynamics of the scattering material. Historically, x-ray TDS was the first tool utilized by people in experimental determination of phonon dispersion …

X-ray Studies of Lattice Dynamics
Analysis of thermal diffuse scattering of x-rays (TDS) has recently shown great promise as a tool for phonon studies, complementing more traditional neutron scattering techniques. Quasi-elastic x-ray scattering from thermally populated phonon modes has been used to study lattice dynamics and phonon …

X-Ray Scattering Study of the Transition Dynamics in Relaxor Ferroelectric Lead (Magnesium(1/3) Niobium(2/3)) Oxygen(3) (Pmn)
Thermal diffuse scattering measurements were performed at several temperatures. A [011] transverse optic soft mode was determined to exist. The temperature dependence of this phonon mode was carefully studied as the transition is approached, and down to 40 K. The q-dependency of the freezing …
