An on-chip Mach-Zehnder interferometer (MZI) hydrogen sensor, applying a double-slot hybrid plasmonic (DSHP) waveguide composed of Si and two Pd disks on both sides as the sensing arm, is designed. The optical confinement factor area can be up to 87%. For MZI sensor with DSHP 14 µm, sensitivity high 11.935 nm/%, corresponding free spectral range (FSR) 15 nm. Furthermore, influenced by structure parameters, which highly adjustable. extinction ratio interference spectra reach over 30 dB. A...
In this paper, a transmissive dual-channel fiber-optic biosensor based on local surface plasmon resonance (LSPR) and (SPR) is designed for the simultaneous detection of rabies virus antibody temperature. traditional SPR sensor structure, it necessary to coat different metal films two channels obtain independent signals in one probe. work, dopamine hydrochloride was used separate peaks. Sensing channel 1 as an immunosensing road by using LSPR effect, coating its with gold nanoparticles...
Abstract The formamidinium lead iodide (FAPbI 3 ) perovskite has emerged as a promising material for high‐efficiency photovoltaic applications. Although power conversion efficiency of more than 26% been achieved, stability issues have hindered its commercial application. In this study, the FAPbI under adverse conditions such humidity, oxygen, ultraviolet light, and temperature fluctuations is systematically reviewed. known effective strategies improving are discussed. Current studies shown...
Schottky heterojunctions based on graphene–silicon structures are promising for high-performance photodetectors. However, existing fabrication processes adopt transferred graphene as electrodes, limiting process compatibility and generating pollution because of the metal catalyst. In this report, photodetectors fabricated using directly grown nanowalls (GNWs) electrodes. Due to metal-free growth process, GNWs–Si with an ultralow measured current noise 3.1 fA Hz−1/2 obtained, as-prepared...
Because of the slow relaxation process according to weak acoustic phonon interaction, photothermionic effect in graphene could be much more obvious than metal film, so a heterojunction photodetector based on is promising for infrared imaging applications. However, 2.3% absorption rate film presents severe limitation. Here, situ grown nanowalls (GNWs) were integrated silicon substrate interfaced with Au nanoparticles. strong and hot-carrier GNWs, as-prepared GNWs/Au/silicon has photo dark...
The allotrope of carbon, biphenylene, was prepared experimentally recently [Fan et al., Science 372, 852–856 (2021)]. In this Letter, we perform first-principles simulation to understand the bonding nature and structure stability possible in-plane heterostructure built by graphene biphenylene. We found that graphene–biphenylene only exhibits along armchair direction, which is connected together strong covalent bonds energetically stable. Then, non-equilibrium molecular dynamics calculations...
