Quasielastic light scattering in silicon

, 2000
A dominant, broad central mode in the Brillouin spectrum of silicon was first reported by Sandercock in 1978. This feature was later ascribed to a two-phonon difference scattering process.

Quasielastic scattering of

, 2018
The quasielastic scattering angular distribution of 17C from a carbon target at 40MeV/nucleon was measured using the inverse kinematics method. The analysis of the experimental data was started using the optical model.

Mapping from quasi-elastic scattering to fusion reactions

EPJ Web of Conferences, 2015
The fusion barrier distribution has provided a nice representation for the channel coupling effects on heavy-ion fusion reactions at energies around the Coulomb barrier.

Halide Perovskite: A Rich Source of Thermal Insulator

Advanced Science, EarlyView.
Halide perovskites exhibit ultralow thermal conductivity driven by intrinsic lattice softness and strong anharmonicity, falling below conventional defect‐engineering limits. Weak metavalent bonding, A‐site rattling, and dynamic octahedral tilting drive phonon scattering to the Ioffe–Regel limit, where wave‐like tunneling replaces particle‐like ...

Correlated Polymer‐Proton Hopping Enables Water‐Independent Fast Proton Transport in Poly(Ionic Liquid) Membranes

Advanced Science, EarlyView.
A polymer chain in motion: backbone, ring, and counterion dynamics interlock across timescales to relay protons through poly(ionic liquid) membranes. ABSTRACT Polymer electrolyte membranes composed of ionic liquids (IL), capable of conducting protons efficiently at elevated temperatures, without external humidification, could transform fuel cell ...

A Time-of-Flight Neutron Backscattering Spectrometer at the China Spallation Neutron Source: Principle, Design, and Its Prospects

Quantum Beam Science
The quasielastic neutron scattering technique is an indispensable tool for probing microscopic dynamics in condensed matter at the nanoscale. However, the lack of a high-resolution spectrometer has restricted comprehensive studies of dynamics in China ...

How Proton Incorporation Reshapes Lattice Dynamics In BaSnO3‐Type Proton Conductors

Advanced Science, Volume 13, Issue 50, 7 September 2026.
Yttrium‐doped BaSnO3 exhibits isotope‐dependent changes in its low‐energy vibrational density of states upon hydration. Comparison of dry, H2O‐, and D2O‐treated samples re‐veals mass‐dependent phonon renormalization linked to proton dynamics near oxygen va‐cancies, providing experimental insight into hydrogen‐coupled lattice excitations in proton ...
