Atomically localized ingredient-dependent interface phonon in heterogeneous solids
Mei Wu, Ruochen Shi, Ruishi Qi +12
Phonons are the primary heat carriers in non-metallic solids. In compositionally heterogeneous materials, the thermal properties are believed to be mainly governed by the disrupted…
Single-dislocation phonons: atomic-scale measurement and their thermal properties
Yuehui Li, Bo Han, Xiaolong Yang +12
Nanoscale defects such as dislocations, have a significant impact on the phonon thermal transport properties in non-metallic materials. To unravel these effects, understanding of d…
Electron microscopy probing electron-photon interactions in SiC nanowires with ultra-wide energy and momentum match
Jinlong Du, Jin-hui Chen, Yuehui Li +4
Nanoscale materials usually can trap light and strongly interact with it leading to many photonic device applications. The light-matter interactions are commonly probed by optical…
Direct observation of local antiferroelectricity induced phonon softening at a SrTiO3 defect
Bo Han, Ruochen Shi, Huining Peng +7
Defects in oxides usually exhibit exotic properties that may be associated with the local lattice dynamics. Here, at atomic spatial resolution, we directly measure phonon modes of…
