Optical waveguides are fundamental components in integrated optics, enabling the confinement of light beams at micron and nanometer scales. The performance of electro-optic materials is the key to realizing waveguide-based modulation devices. Potassium tantalate niobate (KTN) crystals exhibit exceptional quadratic electro-optic effects, making them highly promising for applications in optical waveguides and electro-optic modulators. This study explored a novel, to our knowledge, optical waveguide leveraging the quadratic electro-optic effect of KTN crystals. Buried waveguides with a width of 10 μm were fabricated in KTN crystals using the titanium ion diffusion method. The impact of ion diffusion on the crystal structure of KTN was analyzed using confocal Raman spectroscopy. Based on the optical waveguide, an intensity modulator with a single waveguide and an extinction ratio of 14.2 dB at 1550 nm was developed. The modulator's different modulation functions were evaluated without and with an applied bias voltage. This research offers valuable insights for the design and production of low-driving, efficient electro-optic modulation devices in integrated optics.

Metal–organic frameworks (MOFs) with a substantial surface area and configurable porosity have gained the interest of researchers in energy storage devices and environmental management. Our investigation efficaciously employs a cuboid-shaped nickel and trimesic acid metal–organic framework (Ni-TMA MOF) as a bifunctional high-performance supercapacitor electrode as well as an efficient photocatalyst. The Ni-cuboid-like MOF's structure provides more electroactive sites along with a shorter pathway for electron transfer and electrolyte diffusion, resulting in a high specific capacitance of 236 F g−1 at 1 A g−1. The fabricated electrode exhibits particularly high capacitance retention, with over 98% retention even after 1000 cycles. The photocatalytic activity of the Ni-TMA MOF for the degradation of rhodamine 6G dye was investigated, which revealed that 90% of the dye was degraded in nearly 40 min, which follows the modified Freundlich process. The development of multifunctional materials to address emerging problems is of paramount importance, and this work ensures this possibility, with results showing improved energy storage and photocatalytic capability.

This paper investigates a wireless powered and backscattering enabled sensor network based on the non-linear energy harvesting model, where the power beacon(PB) delivers energy signals to wireless sensors to enable their passive backscattering and active transmission to the access point(AP). We propose an efficient time scheduling scheme for network performance enhancement, based on which each sensor can always harvest energy from the PB over the entire block except its time slots allocated for passive and active information delivery. Considering the PB and wireless sensors are from two selfish service providers, we use the Stackelberg game to model the energy interaction among them. To address the non-convexity of the leader-level problem, we propose to decompose the original problem into two subproblems and solve them iteratively in an alternating manner. Specifically, the successive convex approximation, semi-definite relaxation(SDR) and variable substitution techniques are applied to find a nearoptimal solution. To evaluate the performance loss caused by the interaction between two providers, we further investigate the social welfare maximization problem. Numerical results demonstrate that compared to the benchmark schemes, the proposed scheme can achieve up to 35.4% and 38.7% utility gain for the leader and the follower, respectively.

In ferroelectric (FE) semiconductors with strong spin-orbit coupling, the electron’s spin direction is locked to its momentum by an intrinsic spin-orbit field (SOF) switchable by ferroelectric polarization. This provides a promising platform for novel nonvolatile spintronic devices. Here, we propose exploiting the switchable SOF to realize a FE spin-orbit valve (FE-SOV), where two FE semiconductors are separated by a thin barrier layer. Because of the locking between the SOF and polarization direction, the conductance of the FE-SOV strongly depends on the relative orientation of polarization of the two FE semiconductors. Using a tight-binding model and density functional theory calculations for FE-SOVs based on two-dimensional FE SnTe and Bi, we demonstrate a giant FE-SOV effect that is characterized by the conductance change of several orders in magnitude. Our work enriches spin-orbit physics of ferroelectrics and proposes a new type of all-electric control of a nonvolatile spin-orbitronic device, which holds promise for future electronic and memory applications.

Monitoring of benzo[def]phenanthrene as a toxic component is essential for environmental assessment because of its adverse impact on human health and ecological systems. P-Toluenesulfonic acid-doped polyaniline (PANI) and PANI-graphene quantum dot (PANI-GQD) nanocomposites were fabricated by incorporating graphene quantum dot (GQD) concentrations between 100 and 500 ppm through oxidative chemical polymerization of aniline under acidic conditions at ambient temperature. The materials were analysed using Fourier transform infrared (FT-IR), field emission scanning electron microscopy (FE-SEM), X-ray diffraction (XRD), thermogravimetry analysis (TGA), UV–visible and photoluminescence (PL) spectroscopy, and electrical conductivity measurements. Key findings included significant shifts in FT-IR peaks (C=N stretching from 1651 to 1694 cm⁻1) and an increase in the AB/AP ratio from 0.27 to 0.333, indicating enhanced sp2 hybridization and improved electrical conductivity. XRD analysis showed improved molecular ordering in PANI-GQD nanocomposites. FE-SEM revealed changes in morphology from flat layers to spherical and flaky mixtures with increasing GQD concentrations. Film thickness increased from 13.52 μm (PANI-GQD-1) to 30.07 μm (PANI-GQD-5). The PANI-GQD-3 nanocomposite exhibited the lowest bandgap (2.39 eV) and the highest PL intensity because of enhanced energy transfer between PANI and GQD. Electrical conductivity decreased with increasing GQD concentration, with PANI-GQD-5 showing 2.17 (Ω cm)–1. PANI-GQD-3 successfully detected benzo[def]phenanthrene at concentrations ranging from 0.001 mol L⁻1 to 10 × 10⁻⁹ mol L⁻1 with a limit of detection of 1.5 × 10⁻⁹ mol L⁻1 through gas chromatography. Results demonstrated the potential of PANI-GQD nanocomposites for sensor and biosensor applications. © The Author(s), under exclusive licence to Springer Science+Business Media, LLC, part of Springer Nature 2025.

Magnetic control of nonreciprocal charge transport

Nonreciprocal charge transport (NCT) characterized by unequal resistances for opposite current direction enriches the fundamental physics of electron transport and is promising for potential device applications. Here, we report on a study on the magnetic control of the NCT in two-dimensional systems with different types of spin-orbit coupling (SOC). Based on the Boltzmann transport theory, we first study this effect using a general Hamiltonian model and show that the nonlinear conductivity can be efficiently tuned by the exchange field. In particular, the exchange-field orientation dependence of the nonlinear conductivity reveals significantly distinct relations for different SOCs. We further derive the analytical expressions with the weak-field approximation, which are in good accordance with numerical results. Then, we exemplify this phenomenon in the Ag2Te/Cr2O3 surface based on density functional theory calculations. We predict that the nonlinear conductivity in such a system strongly depends on the surface magnetization orientation of the Cr2O3 layer. Those findings also suggest that measuring the NCT as a function of the exchange-field orientation provides a simple electrical means to quantify the SOC type. Our results are expected to provide a valuable insight into the NCT physics and open avenues for future rectifying devices.

This paper outlines a comprehensive methodology for verifying and validating the functional performance evaluation of high-fidelity radio detection and ranging (RADAR) sensor models at both the raw data level, specifically the range map (RM) and range-Doppler map (RDM), and the detection level. Three key performance parameters (KPPs) are defined at the raw data level: the target's received power, signal-to-noise ratio (SNR), and twoway beam pattern. Four KPPs are identified at the detection level: distance, relative radial velocity, azimuth angle, and elevation angle. This study also introduces three dynamic test scenarios directly applicable to the functional evaluation assessment of RADAR sensor models. Furthermore, a toolchain is presented to integrate real-world test scenarios into the virtual environment, allowing for frame-by-frame validation of the RADAR sensor models' functional evaluation. Quantitative analysis successfully assesses differences between simulations and real measurements, employing the mean absolute percentage error (MAPE) metric. This methodology has been successfully applied to a high-fidelity RADAR sensor model featuring a multiple input and multiple output (MIMO) 2D linear spacing virtual antenna and a complete signal processing toolchain that mimics real RADAR sensors. Results show a strong correlation between the simulation and real measurements, with MAPE values below 7 % for all defined KPPs at raw data and detection levels. Using this methodology, developers can assess whether virtual RADAR sensors are ready for environmental perception during scenario-based automated driving system (ADS) testing.
