Applying the photoexcitation characteristics of vanadium dioxide (VO(2)), a dynamic resonant terahertz (THz) functional device with combination VO(2) film and dual-resonance metamaterial was suggested to realize ultrafast external spatial THz wave active manipulation. The designed realizes pass band at 0.28-0.36 between dual-resonant frequencies, is applied control transmittance wave. More than an 80% modulation depth has been observed in statics experiment, experimental results illustrate...
Utilizing terahertz (THz) waves to transmit data for communication and imaging places high demands on phase modulation. However, until now, it is difficult realize a more than 100° shift in the transmission mode with one-layer structure. In this paper, ring-dumbbell composite resonator nested VO2 nanostructures proposed achieve large shift. It found that structure hybrid an enhanced resonant intensity, which coupled by L-C resonance dipole has been observed. Applying photoinduced transition...
Vanadium dioxide (VO2), with reversible metal-semiconductor transition near room temperature, is a compelling candidate for thermochromic windows. Nanocomposite coatings derived from VO2 nanoparticles are particularly superior to films due their advantages in large-scale preparation, flexible shaping, and regulation of optical properties. In this work, we developed novel method one-step hydrothermal synthesis W-doped (M) nanorods studied application infrared smart On introducing tartaric...
Abstract Tackling the interfacial loss in emerged perovskite‐based solar cells (PSCs) to address synchronously carrier dynamics and environmental stability, has been of fundamental viable importance, while technological hurdles remain not only creating such mediator, but subsequent embedding active layer. This article reports a strategy hydrophobic fluorinated‐gold‐clusters (FGCs) for highly efficient stable PSCs. The p‐type semiconducting feature enables FGC mediator improve by reducing...

Based on...
Abstract Large-scale stretchable strain sensor arrays capable of mapping two-dimensional distributions have gained interest for applications as wearable devices and relating to the Internet Things. However, existing are usually unable achieve accurate directional recognition experience a trade-off between high sensing resolution large area detection. Here, based on classical Mie resonance, we report flexible meta-sensor array that can detect in-plane direction magnitude preloaded strains by...
We have fabricated a metamaterial of metal/semiconductor/metal sandwich nanostrips structure comprising pair gold strips and vanadium dioxide (VO2) strip.

The composition and microstructure of investigated X-ray photoelectron spectroscopy (XPS), diffraction (XRD), field-emission scanning electron microscopy (FE-SEM), atomic force (AFM). results indicated a polycrystalline nature with high crystallinity compact nanostructure for films, concentration +4 valence vanadium is 79.85%. Correlated these, giant transmission...
A WO<sub>3</sub>/RGO film exhibited shorter coloration–bleaching times and larger modulatory range, being attributed to faster Li<sup>+</sup> ion diffusion electron transfer rate.
We present a terahertz (THz) amplitude modulation method with near perfect E-field depths that is based on impedance matching in VO2 thin films during the thermally induced insulator-metal transition (IMT). It was observed matching-induced THz sensitive to resistance switching characteristics of films.

Optical physical unclonable function (PUF) is one of the most promising hardware security solutions, which has been proven to be resistant machine learning attacks. However, disordered structures traditional optical PUFs are usually deterministic once they manufactured and therefore exhibit fixed challenge-response behaviors. Herein, a reconfigurable PUF (R-PUF) proposed demonstrated by using reversible phase transition behavior VO2 nanocrystals combined with TiO2 nanoparticles. Both...
