Zone-folded longnitude acoustic phonons driving self-trapped state emission in colloidal CdSe nanoplate superlattice
Xinyu Sui, Xiaoqing Gao, Xianxin Wu +11
Colloidal cadmium chalcogenide nanoplates are two-dimensional semiconductors that have shown great application prospect for light-emitting technologies. Self-trapped state (STS), a…
Four-dimensional Vibrational Spectroscopy for Nanoscale Mapping of Phonon Dispersion in BN Nanotubes
Ruishi Qi, Ning Li, Jinlong Du +8
Direct measurement of local phonon dispersion in individual nanostructures can greatly advance our understanding of their electrical, thermal, and mechanical properties. However, s…
Creating topological polar structure in a nonpolar matter
Adeel Y. Abid, Yuanwei Sun, Xu Hou +15
Nontrivial topological structures offer rich playground in condensed matter physics including fluid dynamics, superconductivity, and ferromagnetism, and they promise alternative de…
Transmission electron microscopy of organic-inorganic hybrid perovskites: myths and truths
Shulin Chen, Ying Zhang, Jinjin Zhao +8
Organic-inorganic hybrid perovskites (OIHPs) have attracted extensive research interest as a promising candidate for efficient and inexpensive solar cells. Transmission electron mi…
Interlayer Decoupling in 30° Twisted Bilayer Graphene Quasicrystal
Bing Deng, Binbin Wang, Ning Li +8
Stacking order has strong influence on the coupling between the two layers of twisted bilayer graphene (BLG), which in turn determines its physical properties. Here, we report the…
Broad-Spectral-Range Sustainability and Controllable Excitation of Hyperbolic Phonon Polaritons in -MoO3
Weikang Dong, Ruishi Qi, Tiansheng Liu +8
Hyperbolic phonon polaritons (HPhPs) in orthorhombic-phase molybdenum trioxide (-MoO3) show in-plane hyperbolicity, great wavelength compression and ultra-long lifetime, therefo…
