The spin Hall effect (SHE) of light is very weak because the extremely small photon momentum and spin-orbit interaction. Here, we report a strong photonic SHE resulting in measured large splitting polarized at metasurfaces. rapidly varying phase discontinuities along metasurface, breaking axial symmetry system, enable direct observation transverse motion circularly light, even normal incidence. interaction deviates from trajectory prescribed by ordinary Fermat principle. Such broadband may...
Optics On the Edge The ability to isolate stable materials just one atom thick has provided impetus for a new generation of thin films technologies. Often, are conceptually imaged in form an artist's impression as single continuous layers—a crystal sheet atoms. Scanning probe and transmission electron microscopies reveal reality, however, where material resembles patchwork quilt with polycrystals different orientation size separated by grain boundaries forming mosaic. These structures play...
Second-harmonic generation (SHG) has found extensive applications from hand-held laser pointers to spectroscopic and microscopic techniques. Recently, some cleavable van der Waals (vdW) crystals have shown SHG arising a single atomic layer, where the SH light elucidated important information such as grain boundaries electronic structure in these ultra-thin materials. However, despite inversion asymmetry of typical crystal stacking restores symmetry for even numbers layers leading an...
We report efficient nonradiative energy transfer (NRET) from core-shell, semiconducting quantum dots to adjacent two-dimensional sheets of graphene and MoS2 single- few-layer thickness. observe quenching the photoluminescence (PL) individual enhanced PL decay rates in time-resolved PL, corresponding 1-10 ns(-1). Our measurements reveal contrasting trends NRET rate dot van der Waals material as a function The increases significantly with increasing layer thickness graphene, but decreases...
Van der Waals interfaces can be formed by layer stacking without regard to lattice constants or symmetries of individual building blocks. We engineered the symmetry a van interface tungsten selenide and black phosphorus realized in-plane electronic polarization that led emergence spontaneous photovoltaic effect. Spontaneous photocurrent was observed along polar direction absent in perpendicular it. The explained quantum-mechanical shift current reflects geometrical topological nature this...
Higher-order correlated excitonic states arise from the mutual interactions of excitons, which generally requires a significant exciton density and therefore high excitation levels. Here, we report emergence two biexcitons species, one neutral charged, in monolayer tungsten diselenide under moderate continuous-wave excitation. The efficient formation is facilitated by long lifetime dark state associated with spin-forbidden transition, as well improved sample quality encapsulation between...
Coronary microembolization (CME) is a common complication of acute coronary syndrome (ACS) and percutaneous intervention (PCI); Myocardial inflammation, caused by CME, the main cause cardiac injury. TLR4/MyD88/NF-κB signaling plays an important role in development myocardial but its effects on CME remain unclear. To assess protective TAK-242 (TLR4 specific inhibitor) CME-induced injury, explore underlying mechanism.Cardiac function, serum c-troponin I level, microinfarct were examined...
Optical selection rule fundamentally determines the optical transition between energy states in a variety of physical systems from hydrogen atoms to bulk crystals such as GaAs. It is important for optoelectronic applications lasers, energy-dispersive X-ray spectroscopy and quantum computation. Recently, single layer metal dichalcogenide (TMDC) exhibits valleys momentum space with nontrivial Berry curvature excitons large binding energy. However, it unclear how unique valley degree freedom...
Abstract Background Studies on the prospective association of body composition with mortality in US general populations are limited. We aimed to examine this by utilizing data from National Health and Nutrition Examination Survey (NHANES), a representative sample adults, linked Death Index. Methods analysed NHANES 1988–1994 1999–2014, 55 818 participants [50.6% female, baseline mean age: 45.0 years (SE, 0.2)]. Predicted fat mass lean were calculated using validated sex‐specific...
Slip avalanches are ubiquitous phenomena occurring in three-dimensional materials under shear strain, and their study contributes immensely to our understanding of plastic deformation, fragmentation, earthquakes. So far, little is known about the role strain two-dimensional (2D) materials. Here we show some evidence 2D slip exfoliated rhombohedral MoS2, triggered by near threshold level. Utilizing interfacial polarization 3R-MoS2, directly probe stacking order multilayer flakes discover a...
Abstract Understanding the nature of sliding ferroelectricity is fundamental importance for discovery and application two-dimensional ferroelectric materials. In this work, we investigate phenomenon switchable polarization in a bilayer MoS 2 with natural rhombohedral stacking, where spontaneous coupled excitonic effects through asymmetric interlayer coupling. Using optical spectroscopy imaging techniques, observe how released domain wall switches large single domain. Our results highlight...
Open quantum systems consisting of coupled bound and continuum states have been studied in a variety physical systems, particularly within the scope nuclear, atomic, molecular physics. In open effects decay channels are accounted for by indirect non-Hermitian couplings among quasibound states. Here we explore anti-Hermitian coupling plasmonic system spatially manipulating light on nanoscale. We show that utilizing coupling, antennas closely packed only λ/15 separations can be individually...
Excitons in MoS2 dominate the absorption and emission properties of two-dimensional system. Here, we study microscopic origin electroluminescence from monolayer fabricated on a heavily p-type doped silicon substrate. By comparing photoluminescence diode, direct-exciton bound-exciton related recombination processes can be identified. Auger exciton-exciton annihilation bound exciton is observed under high electron-hole pair injection rate at room temperature. We expect direct lifetime to...
