High-Performance Green and Blue Light-Emitting Diodes Enabled by CdZnSe/ZnS Core/Shell Colloidal Quantum Wells
Yunke Zhu, Xiuyuan Lu, Jingjing Qiu +17
The unique anisotropic properties of colloidal quantum wells (CQWs) make them highly promising as components in nanocrystal-based devices. However, the limited performance of green…
Atomic-scale mechanism of enhanced electron-phonon coupling at the interface of MgB thin film
Xiaowen Zhang, Tiequan Xu, Ruochen Shi +7
In this study, we explore the heterointerface of MgB film on SiC substrate at atomic scale using electron microscopy and spectroscopy. We detect ~1 nm MgO between MgB and S…
Nanoscale Cathodoluminescence Spectroscopy Probing the Nitride Quantum Wells in an Electron Microcope

To gain a deeper understanding of the luminescence of multiquantum wells and the factors affecting it on a microscopic level, cathodoluminescence combined with scanning transmissio…
Atomic-Scale Tracking Phase Transition Dynamics of Berezinskii-Kosterlitz-Thouless Polar Vortex-Antivortex
Ruixue Zhu, Sizheng Zheng, Xiaomei Li +8
Particle-like topologies, such as vortex-antivortex (V-AV) pairs, have garnered significant attention in the field of condensed matter. However, the detailed phase transition dynam…
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…
Antiphase boundary in CHNHPbI repels charge carriers while promotes fast ion migrations
