Group-V elemental monolayers were recently predicted to exhibit exotic physical properties such as nontrivial topological properties, or a quantum anomalous Hall effect, which would make them very suitable for applications in next-generation electronic devices. The free-standing group-V monolayer materials usually have buckled honeycomb form, contrast with the flat graphene monolayer. Here, we report epitaxial growth of atomically thin element antimony on Ag(111) substrate. Combined study...
Generating electron coherence in quantum materials is essential optimal control of many-body interactions and correlations. In a multidomain system this signifies nonlocal emergence collective phenomena, particularly layered 2D possessing novel electronic structures high carrier mobilities. Here we report ac induced dispersed MoS2 flake domains, using coherent spatial self-phase modulation (SSPM). The gap-dependent nonlinear dielectric susceptibility χ(3) measured surprisingly large, where...
Abstract 2D anisotropic Dirac cones are observed in χ 3 borophene, a monolayer boron sheet, using high‐resolution angle‐resolved photoemission spectroscopy. The centered at the X and X′ points. data also reveal that hybridization between borophene Ag(111) is very weak, which explains preservation of cones. As has been predicated to be superconductor, results may stimulate further research interest novel physics such as interplay Cooper pairs massless fermions.
Black phosphorus (BP), an elemental semiconductor, has attracted tremendous interest because it exhibits a wealth of interesting electronic and optoelectronic properties in equilibrium condition. The nonequilibrium structures bulk BP under periodic field laser remain unexplored, but can lead to intriguing topological properties. Here we show that, the irradiation circularly polarized light (CPL), photon-dressed Floquet-Dirac semimetal state, which be continuously tuned by changing direction,...
Planar borophene, the truly 2D monolayer boron, has been independently successfully grown on Ag(1 1 1) by two groups (2016 Nat. Chem. 8 563 and 2015 Science 350 1513), which received widespreading attentions. The superconducting property not unambiguously observed, is unexpected because light element boron should have strong electron–phonon coupling. To resolve this puzzle, we show that transition temperature Tc of β12 borophene effectively suppressed substrate-induced tensile strain...
Intrinsic valley polarization can be obtained in VSe2 monolayers with broken inversion symmetry and time reversal symmetry. First-principles investigations reveal that the magnitude of splitting magnetic induced by spin-orbit coupling reaches as high 78.2 meV linearly tuned biaxial strain. Besides conventional polarized light, hole doping or illumination light proper frequency offer effective routes to realize polarization. Moreover, monolayer breaks not only degeneracy but also three-fold...
The past decade has witnessed numerous discoveries of two-dimensional (2D) semimetals and insulators, whereas 2D metals are rarely identified. Borophene, a monolayer boron sheet, recently emerged as perfect metal with unique structure electronic properties. Here we study collective excitations in borophene, which exhibit two major plasmon modes low damping rates extending from infrared to ultraviolet regime. anisotropic 1D originates tilted Dirac cones analogous that heavily doped...

Single-layer transition-metal dichalcogenides (TMDs) such as MoS2 and MoSe2 exhibit unique electronic band structures ideal for hosting many exotic spin-orbital orderings. It has been widely accepted that Rashba spin splitting (RSS) is linearly proportional to the external field in heterostructure interfaces or potential gradient polar materials. Surprisingly, an extraordinary nonlinear dependence of RSS found semiconducting TMD monolayers under a gate field. In contrast small constant...

Crop mapping using remote sensing is a reliable and efficient approach to obtaining timely accurate crop information. Previous studies predominantly focused on large-scale regions characterized by simple cropping structures. However, in complex agricultural regions, such as China’s Huang-Huai-Hai region, the high diversity fragmented cropland localized areas present significant challenges for mapping. To address these challenges, this study introduces landscape-clustering zoning strategy...
Accurate determination of reaction barrier is crucial in chemical engineering since it directly associated with the rate and path. Whereas massive quantum calculations relying on commercial software have been reported for understanding mechanisms, solvent effect still poorly understood. The difficulty originates partially from ill capture inhomogeneous structure around site. Herein, we propose a density functional theory (RxDFT) by combining calculating intrinsic energy classical addressing...
