Abstract The authors report an indium tin oxide (ITO) decorated solar-blind deep ultraviolet photodetectors (PDs) based on high quality β -Ga 2 O 3 single crystal microwires (MWs). An ultrahigh photo-to-dark current ( I photo / dark ) ratio ∼10 7 of the PDs has been realized. Compared with In/ /In metal-semiconductor-mental (MSM) PD, device ITO as interlayers between In and show excellent performances, such responsivity 1720.2 A W −1 438.8 under 260 nm illumination reverse forward bias,...
Siphons have been known and used since ancient times are still widely used. We re-examine the siphon process recognize that existing classic formula of flow velocity a is only applicable to continuous flow; however, may be discontinuous flow. This study proposes new formulas, which can cover consider influence release air from liquid on velocity. Sixteen experiments were performed validate our proposed method. The main results show (a) for some schemes, calculated values large errors maximum...
With progress in fifth-generation techniques, more advanced techniques are available for disabled people. Disability table tennis has also benefited from the new technology. In this paper, a portable and low-cost triboelectric nanogenerator wheelchair monitoring systems is proposed. It was applied athletes’ monitoring. The consists of Kapton, polyurethane films, foam supporting layer. materials have flexible characteristics. Therefore, device no influence on exercise performance. Due to...
One of the main desired capabilities smart grid is ‘self‐healing’, which ability to quickly restore power after a disturbance. Due critical outage events, customer demand or load at times disconnected shed temporarily. While deterministic optimisation models have been devised help operators expedite recovery by harnessing flexibility grid's topology (i.e. transmission line switching), an important issue that remains unaddressed how cope with uncertainty in generation and encountered during...
With the increase in rainfall, landslides occur on many gentle slopes mountainous areas of southeast China. Gentle have a particular dual geological structure, i.e., lower part is gravel soil layer with good water permeability, and surface clay relatively poor permeability. Under conditions heavy slope this structure likely to collect temporary confined water. The intermittent creep upper caused by floating force water, which causes landslide disasters. that bring about are related not only...
A metal-insulator-metal (MIM) waveguide system consisting of a MIM waveguide, ring cavity, and semi-ring cavity is proposed. Using the finite element method, transmission characteristics are discussed under different geometry parameters. By detecting resonance wavelength varying refractive index, sensing performance analyzed. The proposed structure can be used as index sensor with maximum sensitivity 2412 nm/RIU. Due to isolating independent tuning double resonances realized by changing...
A surface plasmon polaritons (SPPs) waveguide structure composed of a metal–insulator–metal with baffle, special square cavity (SSC), and ring (RC), is proposed to realize independent tuning in triple Fano resonances. Using the finite element method, magnetic field distributions optical transmission spectra are analyzed detail. The simulation results show that achieves resonances originated from two different mechanics. One occurs RC, others occur SSC. By regulating parameters SSC these can...
We propose a plasmonic waveguide comprising single-layer graphene, silica dielectric layer, and silicon grating substrate to realize dual-channel slow surface plasmon polaritons. The results from the introduction of two kinds periodic structures with defects in waveguide. According Bragg equation, we match appropriate structure parameters ensure light working around λ1=9369.1nm (32 THz) λ2=7138.2nm (42 THz). influence on effect is discussed, largest value normalized delay bandwidth product...
Slope siphon drainage is a convenient and efficient above-ground method that free of manual power can effectively maintain the stability potential landslides prevent loss life property. The complex engineering topography inevitably requires use drains with total length more than 150 m horizontal section 80 m, which significantly increases difficulty calculating capacity thus affects actual utilization project. traditional flow rate equation does not apply to long-pipe conditions, especially...
Unlike traditional optical vortex (OV), helico-conical beams (HCOBs) carry orbital angular momentum (OAM) related to the beam's radius and exhibit a helical intensity pattern, drawing widespread attention in fields such as communication tweezers. In this study, we introduce two independent power-exponents into HCOB configuration employ spin-isolated geometric phase metasurfaces simultaneously generate dual bi-power-exponent (BPE-HCBs). This innovative approach allows unprecedented control...

In addition, we also studied...
Siphon drainage, which is applicable in engineering as one of the effective methods to maintain slope stability, has many advantages, including no additional power requirements, simple construction, and low construction cost. However, due topographic constraints high farmland occupation costs, most projects inevitably use pipes with a total length more than 100 m horizontal sections 50 for drainage. The increase pipe serious adverse effects on siphon drainage process, limiting its capacity...
