Lots of research have focused on the core/shell structure nanocomposites owing to their synergistic effect that were considered as most promising high-performance microwave absorbers (MAs). However, excellent comprehensive properties MAs are still in urgent need. Herein, positive and reverse CoxFe3–xO4/MoS2 (x = 1.5, 0.75 0.5) MoS2/CoxFe3–xO4 elaborately produced through an inexpensive two-step hydrothermal process. It was found samples exhibited a much smaller optimal reflection loss...

Efficient regulation of thermal radiation is an effective way to conserve energy consumption buildings. Because windows are the least energy-efficient part buildings, their highly demanded, especially in changing environment, but still a challenge. Here, by employing kirigami structure, we design variable-angle reflector as transparent envelope for modulation. The can be easily switched between heating and cooling modes loading different pre-stresses, which endow with ability temperature...
Abstract Thermo‐optic (TO) phase shifters are very fundamental units in large‐scale active silicon photonic integrated circuits (PICs). However, due to the limitation of microheater materials with a trade‐off between heating efficiency and absorption loss, designs reported so far typically suffer from slow response time, high power consumption, low yields, on. Here, an energy‐efficient, fast‐responding, low‐loss TO shifter is demonstrated by introducing hydrogen‐doped indium oxide (IHO)...
Abstract Mode‐division multiplexing (MDM) introduces a new dimension to on‐chip optical interconnection, where the multimode switch is one of core components. However, researchers are still struggling reduce chip size and response time, despite great efforts being made. Here, compact, scalable, fast‐response 2 × supporting four modes demonstrated based on specific inverse design. The device consists two CB couplers (including mode converters, interference couplers, crossings) thermo‐optic...
Here, the microwave-absorbing properties of 1-ethyl-3-methylimidazolium and 1-butyl-3-methylimidazolium ([E BMIm]+-based) room-temperature ionic liquids (ILs) with different anions were systematically investigated by measuring dielectric in 1–14 GHz microwave-frequency range. First, [E BMIm]+-based ILs studied a typical open-ended coaxial probe system. The results showed that real part permittivity values decreased from 13 to 4 loss tangent 5.91 0.24, meaning displayed high dielectric-loss...
Infrared solar cells are regarded as candidates for expanding the spectrum of c-Si cells, and window electrodes usually transparent conductive oxide (TCO) such widely used indium tin material. However, due to low transmittance TCO in near-infrared region, most light cannot penetrate electrode be absorbed by active layer. Here, propose a simple procedure fabricate materials with high electrical conductivity, namely hydrogen-doped (IHO) films prepared room temperature magnetron sputtering. The...
It is generally believed that the matching of electromagnetic (EM) impedance or making best interface polarization an efficient way to achieve a good EM wave absorbing capability. Herein, mixed-dimensional C-MoS2 based magnetic van der Waals heterostructures (vdWHs) were elaborately designed and successfully synthesized through catalytic decomposition C2H2 over Fe3O4–MoS2. By controlling pyrolysis temperature, "3-0-2" type heterostructured C–Fe3O4–MoS2 ternary nanohybrid consisting...
We propose an all-dielectric hollow annular groove ultra-broadband metamaterial absorber (A-D ILMMA) based on imidazole ionic liquids, which is freed of metallic substrate and can offer extremely wide bandwidth electromagnetic absorption prominent polarization angle range. When the liquid 1-ethyl-3-methylimidazolium Tetrafluoroborate ([EMIM][BF4]) with a high conductivity dielectric loss factor arranged into unit cells 6 mm total thickness, nearly perfect impedance matching be achieved in...
Abstract Designing and fabricating high-performance transparent conductive oxides (TCOs) is an attractive area for optoelectronic devices that require both high transparency electrical conductivity. In this study, we introduce a hydrogen doping of indium oxide (IHO) as TCO material with enhanced while maintaining conductivity by optimizing the carrier mobility, concentration, thickness. The typical IHO thickness 200 nm exhibits relatively lower concentration (~2.10*10 20 cm −3 ), compared to...
Abstract By controlling the pyrolysis temperature, core/shell/shell structured Fe/Fe 5 C 2 /carbon nanotube bundles (Fe/Fe /CNTBs), 3 C/helical carbon nanotubes C/HCNTs) and C/chain-like nanospheres C/CCNSs) with high encapsulation efficiency could be selectively synthesized in large-scale by water-assisted chemical vapor deposition method. Water was proved to play an important role growth process. Because of α-Fe nanoparticles tightly wrapped two layers, obtained nanohybrids showed...
