The optical absorption of graphene layers prepared on top a one-dimensional photonic crystal (1DPC) is investigated theoretically. with 1DPC enhanced greatly over broad spectral range due to photon localization. can also be tuned by varying either the incident angle or distance between and 1DPC.
The optical absorption of monolayer MoS2 on top one-dimensional photonic crystal (1DPC) or metal films with spacer layers is theoretically investigated by extracting the permittivity from existing experimental results [K. F. Mak et al., Phys. Rev. Lett. 105, 136805 (2010)]. graphene 1DPC across a broad spectral range substantially enhanced because localization at micro-cavity films. can be tuned varying either distance between and back reflector thickness cover layers.
Independently tunable biaxial color pixels, composed of isolated nanosquare dimers, are demonstrated in this study. These pixels capable displaying a full range colors under linear-polarization dependent reflection mode. The metasurface is constructed by arranging LiNbO 3 nanodimers on PDMS substrate. By exciting strong magnetic dipole (MD) resonance and effectively suppressing other multipolar resonances using surface lattice resonances, the researchers achieved single peak with bandwidth...
We investigate THz absorption properties of graphene-based heterostructures by using characteristics matrix method based on conductivity. demonstrate that the proposed structure can lead to perfect because strong photon localization in defect layer heterostructure. The may be tuned continuously from 0 100% controlling chemical potential through a gate voltage. By adjusting incident angle or period number two PCs with respect graphene layer, one tailor maximum value. position peaks changing...
Active optical metadevices have attracted growing interest for the use in nanophotonics owing to their flexible control of optics. In this work, by introducing phase-changing material Ge2Sb2Te5 (GST), which exhibits remarkably different properties crystalline states, we investigate active radiation manipulation a resonant silicon metasurface. A designed double-nanodisk array supports strong toroidal dipole excitation and an obvious electric response. When GST is added, response suppressed,...
A graphene MEMS tunable narrowband filter with minimal deformation (<2 pm), high voltage sensitivity (>400 nm V −1 ), bandwidth (>200 nm) was proposed, achieving full-color display within a single pixel, color gamut reaching 214% of sRGB.
Strain engineering is a very effective method to continuously tune the electronic, topological, optical and thermoelectric properties of materials. In this work, strain-dependent phonon transport recently-fabricated antimonene (Sb monolayer) under biaxial strain investigated from combination first-principles calculations linearized Boltzmann equation. It found that ZA dispersion with less than -1\% gives imaginary frequencies, which suggests compressive can induce structural instability....
With the coming era of big data and rapid development widespread applications Geographical Information Systems (GISs), geocoding technology is playing an increasingly important role in bridging gap between non-spatial resources spatial various fields. However, Chinese faces great challenges because complexity address string format Chinese, which contains no delimiters words, poor management resulting from existence multiple authorities spread among different governmental agencies. This paper...
Online charged electrical vehicles (EVs) with segmental wireless power supply obtain energy from tracks without a physical cable contact while traveling. When vehicle moves one track to another, the coils should switch accordingly provide continually at various positions. As secondary coil fixed in along primary mounted track, mutual inductance of these two changes accordingly, which results varying phase angle that current lags voltage resonant circuit side. The paper presents method decide...
Phonon transport in group-VA element (As, Sb and Bi) monolayer semiconductors has been widely investigated theory, and, of them, (antimonene) recently synthesized. In this work, phonon SbAs is with a combination first-principles calculations the linearized Boltzmann equation. It found that lattice thermal conductivity lower than those both As Sb, corresponding sheet conductance 28.8 W K-1 at room temperature. To understand group velocities lifetimes As, are calculated. The calculated results...
The construction of biomimetic nanozymes with efficient catalytic activities, low costs, and robust stability is fundamentally challenging but practically meaningful for biomedicine, immunoassays, catalysis, environmental applications. Herein, we present a facile one-step strategy to fabricate hemoglobin–gold nanoparticle (Hb–AuNP) system by using hemoglobin (Hb) as an stabilizer reducing agent. Remarkably, the Hb–AuNPs exhibit good dispersion high under harsh conditions (temperature, pH,...
