Rhombohedral-stacked transition-metal dichalcogenides (3R-TMDs), which are distinct from their hexagonal counterparts, exhibit higher carrier mobility, sliding ferroelectricity, and coherently enhanced nonlinear optical responses. However, surface epitaxial growth of large multilayer 3R-TMD single crystals is difficult. We report an interfacial epitaxy methodology for several compositions, including molybdenum disulfide (MoS 2 ), diselenide, tungsten disulfide, niobium sulfoselenide. Feeding...
Low-dimensional water transport can be drastically enhanced under atomic-scale confinement. However, its microscopic origin is still debate. In this work, we directly imaged the atomic structure and of two-dimensional islands on graphene hexagonal boron nitride surfaces using qPlus-based force microscopy. The lattice island was incommensurate with surface but commensurate owing to different electrostatics. area-normalized static friction diminished as area increased by a power ~-0.58,...
Entangled photon-pair sources are pivotal in various quantum applications. Miniaturizing the devices to meet requirement limited space applications drives search for ultracompact entangled sources. The rise of two-dimensional (2D) semiconductors has been demonstrated as However, generation rate and purity relatively low, strong photoluminescence 2D also makes operational wavelength range limited. Here, we use spontaneous parametric down conversion (SPDC) rhombohedral boron nitride (rBN) a...
Optical nonlinearities are one of the most fascinating properties two-dimensional (2D) materials. While tremendous efforts have been made to find and optimize second-order optical nonlinearity in enormous 2D materials, opportunities explore higher-order ones elusive because much lower efficiency. Here, we report giant high odd-order centrosymmetric correlated van der Waals insulator manganese phosphorus triselenide. When illuminated by two near-infrared femtosecond lasers, sample generates a...
A direction of arrival (DOA) estimation method for coherent signals is proposed based on an improved convolutional neural network (CNN) with attention mechanism. The real, imaginary and phase components the covariance matrix are employed as CNN multi-channel inputs. regression model adopted output which avoids grid mismatch problem caused by multi-classification output. Moreover, to enhance accuracy estimation, mechanism added CNN, could give more weight main features effectively. simulation...
Anthraquinones (AQS) represent a group of secondary metallic products in plants. AQS are often naturally occurring plants and microorganisms. In previous study, we found that were produced by enzymatic browning reaction Chinese chestnut kernels. To find out whether non-enzymatic the kernels could produce too, extracted from three groups kernels: fresh kernels, browned contents determined. High performance liquid chromatography (HPLC) nuclear magnetic resonance (NMR) methods used to identify...
