One key challenge in developing postsilicon electronic technology is to find ultrathin channel materials with high charge mobilities and sizable energy band gaps. Graphene can offer extremely mobilities; however, the lack of a gap presents significant barrier. Transition metal dichalcogenides possess thickness-tunable gaps; their are relatively low. Here we show that black phosphorus has room-temperature on order 10(4) cm(2) V(-1) s(-1), which about 1 magnitude larger than silicon. We also...
Anisotropic optical and transport properties of monolayer ReS2 fabricated by mechanical exfoliation are reported. Transient absorption measurements with different polarization configurations sample orientations reveal that the coefficient transient both anisotropic, maximal minimal values occurring when light is parallel perpendicular to Re atomic chains, respectively. The about a factor 2.5 values. By resolving spatiotemporal dynamics excitons, it found diffusion excitons moving along...
Sixteen cotton cultivars widely planted in China were sowed under five different drought concentrations (0, 2.5, 5, 7.5, and 10%) using PEG6000 to screen the indices of resistance identification explore cultivars. Eighteen physiological including root, stem, leaf water contents (RWC, SWC, LWC), net photosynthetic rate (Pn), maximum photochemical quantum yield (Fv/Fm), actual (ϕPSII), non-photochemical quenching coefficient (NPQ), potential (LWP), osmotic (ψs), relative conductivity (REC),...
We report a transient absorption microscopy study of charge carrier dynamics in bulk MoS2 crystals at room temperature. Charge carriers are injected by interband 555-nm pulse, and probed measuring differential reflection time-delayed spatially scanned 660-nm pulse. find an intervalley transfer time about 0.35 ps, energy relaxation hot on the order 50 lifetime 180 ps. By monitoring spatiotemporal carriers, we obtained diffusion coefficient thermalized electrons 4.2 cm2/s, corresponding to...
Spatiotemporal dynamics of excitons in monolayer and bulk WS2 at room temperature is studied by transient absorption microscopy the reflection geometry. Excitons are formed from photocarriers injected a tightly focused 390 nm pump pulse, monitored detecting different time-delayed spatially scanned 620 probe pulse. We obtain exciton lifetimes 22 ± 1 110 10 ps WS2, respectively. Both independent density, showing absence multi-exciton recombination processes. Exciton diffusion coefficients 60...
We study valley and spin dynamics in monolayer molybdenum diselenide by polarization-resolved femtosecond transient absorption spectroscopy. Valley- spin-polarized excitons are injected a circularly polarized laser pulse, with an excess energy of 120 meV. Relaxation the polarization is time-resolved measuring dynamical circular dichroism linearly probe pulse tuned to 790 nm, peak exciton resonance MoSe2. obtain relaxation time 9 ± 3 ps at room temperature, which least one order magnitude...
In this study, resistance to sulfate attack and a chemo-damage-transport model of ions for tunnel lining concrete under the action loading flowing groundwater are investigated. The results show that in initial stage erosion, relative dynamic elastic modulus ion concentration increase gradually. However, subsequent decreases gradually, accelerates. defects tensile zone compressive can be expanded closed, respectively, loading. Meanwhile, corroded groundwater. Therefore, is highest second...
SUMMARY Drought stress significantly affects cotton's net photosynthetic rate ( A ) by restraining stomatal g s and mesophyll conductance m as well perturbing its biochemical process, resulting in yield reductions. Despite the significant progress dissecting effects of drought on photosynthesis, variability observed , mechanisms contributing to that under dynamic conditions are poorly understood. For reason, a controlled‐environment experiment with two cotton genotypes (Dexiamian 1,...
Abstract The corrosion of aluminum alloys (AA) caused by fungi has been considered as the typical reason causing failure aviation materials, but its mechanism is still unclear. In this work, AA 7075 induced Fungus Aspergillus terreus with continued organic carbon starvation was investigated in artificial seawater. Results indicate that A. can survive and form a biofilm on surface, then accelerate corrosion. pitting more severe biotic environments, it closely related to initial spore...
