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…
Phonon transition across an isotopic interface
Ning Li, Ruochen Shi, Yifei Li +13
Natural materials usually consist of isotopic mixtures, for which different isotopic ratios can lead to distinct material properties such as thermal conductivity and nucleation pro…
Tunable Interband Transitions in Twisted h-BN/Graphene Heterostructures
Bingyao Liu, Yu-Tian Zhang, Ruixi Qiao +12
In twisted h-BN/graphene heterostructures, the complex electronic properties of the fast-traveling electron gas in graphene are usually considered to be fully revealed. However, th…
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…
Suppression of ferromagnetism and influence of disorder in silicon-substituted CeRh6Ge4
Y. J. Zhang, Z. Y. Nie, R. Li +10
We report a study of isoelectronic chemical substitution in the recently discovered quantum critical ferromagnet CeRhGe. Upon silicon-doping, the ferromagnetic ordering tem…
