Optical modulators with ultrahigh speed, small footprint, large bandwidth, robust athermal operation, and complementary metal-oxide semiconductor (CMOS) compatibility are important devices for optical communication computing applications. Compared to the conventional modulators, graphene have attracted great interest due their bandwidth an ultracompact footprint. However, practical applications limited by trade-off between speed a critical issue of temperature tolerance. In this work, we...
Biological ion channels rapidly and selectively gate transport through atomic-scale filters to maintain vital life functions. We report an transistor exhibiting ultrafast highly selective controlled by electrical gating in graphene around 3 angstroms height, made from a single flake of reduced oxide. The diffusion coefficient reaches two orders magnitude higher than the bulk water. Atomic-scale shows threshold behavior due critical energy barrier for hydrated insertion. Our situ optical...
The Casimir interaction between two parallel metal plates in close proximity is usually thought of as an attractive interaction. By coating one object with a low-refractive index thin film, we show that the objects same material can be reversed at short distances and preserved long so remain without contact specific distance. With such stable equilibrium, experimentally demonstrate passive trapping vicinity another nanometer scale, requiring any external energy input. This equilibrium...
With recent emergence of wearable electronic devices, flexible and stretchable transparent electrodes are the core components to realize innovative devices. The copper nanowire (CuNW) network is commonly chosen because its high conductivity transparency. However, junction resistances low aspect ratios still limit further performance. Herein, a large-scale semiembedded CuNW conductive film (TCF) was fabricated by electrolessly depositing Cu on electrospun poly(4-vinylpyridine) polymer...
The condensation of half-light half-matter exciton polaritons in semiconductor optical cavities is a striking example macroscopic quantum coherence solid-state platform. Quantum possible only when there are strong interactions between the provided by their excitonic constituents. Rydberg excitons with high principal value exhibit dipole-dipole cold atoms. However, constituent that an excited state, namely (REPs), have not yet been experimentally observed. Here, we observe formation REPs...
Single photon emitters (SPEs) are critical building blocks needed for quantum science and technology. For practical applications, large-scale room-temperature solid-state platforms required. Color centers in layered hexagonal boron nitride (hBN) have recently been found to be ultra-bright stable SPEs at room temperature. Yet, scale up information processing, large tuning range of single energy is demanded wavelength division multiplexing key distribution, where indistinguishability not...
The single crystalline submicrotubes of a small organic functional molecule, 2,4,5-triphenylimidazole (TPI), were successfully prepared with facile method. A series characterizations indicated that the tubes obtained from rolling followed by seaming preorganized two-dimensional sheet-like structure, whose formation was due to efficient cooperation several molecular recognition elements. length and diameter TPI can be readily controlled adjusting experimental conditions. as-prepared have...
Amino-terminated ionic liquid assisted multiphoton photoreduction (IL-MPR) was developed for the direct writing of subwavelength gold nanostructures in AuCl4- ions aqueous solution by femtosecond laser. It revealed that carbon chain length crucial morphology and size control nanostructures. A 228 nm width nanostructure, which beyond optical diffraction limit, fabricated matching between IL power scanning speed laser beam. The measured conductivity is same order as bulk gold. Furthermore, we...
Spontaneous symmetry breaking is a universal concept throughout science. For instance, the Landau-Ginzburg paradigm of translational underlies classification nearly all quantum phases matter and explains emergence crystals, insulators, superconductors. Usually, consequences invariance are studied in large systems to suppress edge effects which cause undesired breaking. While this approach works for investigating global properties, studies local observables their correlations require access...
Abstract The dehydrogenation of bioethanol to acetaldehyde and hydrogen is a sustainable process, owing the atom‐economical transformation easy separation products. However, oxide‐supported Cu catalysts show low selectivity because considerable side reactions caused by their oxygen‐rich surfaces. A conventional carbon‐supported catalyst shows high selectivity, but quickly deactivated migration agglomeration copper particles. Here, we have produced highly porous nitrogen‐rich carbon support...
