Time-reversal symmetry (TRS) is pivotal for materials' optical, magnetic, topological, and transport properties. Chiral phonons, characterized by atoms rotating unidirectionally around their equilibrium positions, generate dynamic lattice structures that break TRS. Here, we report coherent chiral driven circularly polarized terahertz light pulses, polarize the paramagnetic spins in cerium fluoride a manner similar to of quasi-static magnetic field on order 1 tesla. Through time-resolved...
Topological phonons and magnons potentially enable low-loss, quantum coherent, chiral transport of information energy at the atomic scale. Van der Waals magnetic materials are promising to realize such states due their recently discovered strong interactions among electronic, spin, lattice degrees freedom. Here, we report first observation coherent hybridization in monolayer antiferromagnet FePSe3 by cavity-enhanced magneto-Raman spectroscopy. The robust magnon-phonon cooperativity 2D limit...
Abstract Zinc oxide is a very promising material for short‐wavelength light‐emitting devices due to its large band gap and high exciton binding energy. Although great progress has been made in recent years, p‐type doping control over native defects introduced during or after growth are still significant problems that hinder the development of efficient ZnO based optoelectronic devices. Here we demonstrate versatile method n‐type nanorods from same solution at temperature as low 90 °C, where...
Abstract Dielectric films are the foundation of power electronic equipment for energy storage in capacitors. However, typical dielectric exhibit undesirable density and thermal stability, limiting its further application advanced field. For both pure polymers composites‐based dielectrics, macromolecular matrix greatly determines performances. This paper summarizes research progress all‐organic polymer materials from perspective molecular structure design. Systematic comparisons on...
A silicone-containing dynamic hindered urea bond for flexible electronic substrates is developed with enhanced mechanical strength and healing ability simultaneously.
Molecular aggregates with environmental responsive properties are desired for their wide practical applications such as bioprobes. Here, a series of smart near-infrared (NIR) luminogens hyperlipidemia (HLP) diagnosis is reported. The these molecules exhibit twisted intramolecular charge-transfer effect in aqueous media, but aggregation-induced emission highly viscous media due to the restriction motion. These aggregates, which can autonomously respond different environments via switching...
Data contamination -- the accidental consumption of evaluation examples within pre-training data can undermine validity benchmarks. In this paper, we present a rigorous analysis effects on language models at 1B and 8B scales machine translation task. Starting from carefully decontaminated train-test split, systematically introduce various stages, scales, formats to isolate its effect measure impact performance metrics. Our experiments reveal that with both source target substantially...
Abstract Motivated by recent studies on the cluster mott insulator candidate compound Nb 3 Cl 8 , we perform 93 and 35 nuclear magnetic resonance (NMR) measurements to investigate its electron correlations. Below structural transition temperature T s ~ 97 K, all satellites of NMR spectra split into three distinct peaks, which suggest a symmetry lowering due transiton could be attribute change Nb-Nb bond-lengths clusters. The spin-lattice relaxation rate 1/ 1 devided increases upon cooling...
We open-source SMOL (Set of Maximal Overall Leverage), a suite training data to unlock translation for low-resource languages (LRLs). has been translated into 115 under-resourced languages, including many which there exist no previous public resources, total 6.1M tokens. comprises two sub-datasets, each carefully chosen maximum impact given its size: SMOL-Sent, set sentences broad unique token coverage, and SMOL-Doc, document-level source focusing on topic coverage. They join the already...
Spin in semiconductors facilitates magnetically controlled optoelectronic and spintronic devices. In metal halide perovskites (MHPs), doping magnetic ions is proven to be a simple efficient approach introducing spin momentum. this work, we present facile ion protocol through the vapor-phase insertion reaction chemical vapor deposition (CVD)-grown ultrathin Cs3BiBr6 perovskites. The Fe-doped bismuth (Fe:CBBr) demonstrate that iron spins are successfully incorporated into lattice, as revealed...
Silicone-containing dynamically hindered urea bonds are developed as a smart insulating material for power equipment and electronic devices. In this work, silicones constructed by isocyanate–piperazine-based dynamic with cross-linking degree adjusted glycerol. Healing recycling based on dielectric properties mainly emphasized in study. We find that not only heal the cut-damaged feature of silicone but also enable property recovery. A healing efficiency above 95% 90% insulation performance...
Imidazoles are widely used as curing agents and accelerators for fabricating crosslinked epoxy materials applied in electrical electronic fields. However, the intrinsic chemical structure of imidazole derivatives would greatly influence polymerisation process, further change properties, which was not emphasised. To achieve an in-depth understanding, commonly only containing pyridine-type nitrogen with both pyridine pyrrole-type were selected this study. Electrical properties including...
The evolution of excitons from 2D to 3D is great importance in photo-physics, yet the layer-dependent exciton polarizability hasn't been investigated semiconductors. Here, we determine polarizabilities for 3- 11-layer black phosphorus-a direct bandgap semiconductor regardless thickness-through frequency-resolved photocurrent measurements on dual-gate devices and unveil carrier screening effect relatively thicker samples. By taking advantage broadband spectra, are also able reveal response...
