Summary: Compared to Si, GaAs has advantages such as high carrier mobility and energy conversion efficiency, making it a leading competitor in optoelectronics and solar energy conversion. This research demonstrates the electrodeposition and controlled alloying of polycrystalline InxGa1-xAs films at ambient pressure and near-room temperature using the electrochemical liquid-liquid-solid (ec-LLS) process.

Summary: In this article, the static and dynamic characterizations of semiconductors with different materials at room temperature and cryogenic temperature are evaluated and compared. The results show that silicon and gallium nitride-based semiconductors have improved performances at low temperature, while silicon carbide-based semiconductors exhibit reduced performance. These evaluation results can guide cryogenic power electronics applications and future semiconductor characterization research.

Summary: A new copper indium selenide with an orthorhombic crystal structure was synthesized at 800 degrees C. It emits intense photoluminescence at 657 nm and exhibits a direct band gap with an energy close to the photoluminescence position. The compound also shows n-type conductivity and strong nonlinear third-harmonic generation.

Summary: The study aims to investigate the impact of bulk vibrational properties and interfacial structure on thermal transport at interfaces in wide band gap semiconductor systems. The results suggest that thermal conductance depends on the bulk phonon properties of the softer material and the interfacial structure, rather than just the vibrational similarity between the two materials.

Summary: The study introduces a non-wide band gap semiconductor ultraviolet photodetector utilizing silicon nanowire arrays, which exhibit sensitivity to UV light but insensitivity to visible and infrared light. This novel device shows promise for sensitive UV photodetectors, with characteristics comparable to or even better than traditional wide band gap semiconductor devices.

Summary: In this study, a photonic-assisted space-frequency two-dimensional (2D) compressive radar receiver is proposed to achieve high-resolution detection in wide-range scenarios. The system employs spatially adaptive photonic projection basis for compression in the space dimension and photonic compressive sensing for compression in the frequency dimension. The proposed receiver overcomes the resolution deterioration problem of existing photonic compressive receivers and enables wide-range radar detection and inverse synthetic aperture radar (ISAR) imaging with high resolution.

Summary: Using first-principles calculations, alkaline earth tellurides MTe (M = Sr or Ba) are shown to be promising wide-band-gap semiconductors that can be ambipolarly doped and transparent to visible light. With large direct band gaps (3.74 eV for SrTe and 3.09 eV for BaTe), 100 nm thick MTe films exhibit significant transmittance (over 80%) for visible light. The effective mass of electrons and holes in MTe is predicted to be small (<1 m0), enabling high carrier mobilities.

Summary: This study successfully prepared a unique photocatalyst composed of CoP and ZnIn2S4 (ZIS) through electrostatic self-assembly method, exhibiting significantly enhanced photocatalytic performance and excellent stability. These results are attributed to the large/intimate contact interface and the photo/electro-chemical properties of ZIS and CoP, improving light absorption, facilitating photoelectron transport and suppressing charge recombination.

Summary: This paper presents two novel cruciate ligament structures that contribute significantly to lightweight design of metamaterials, band gap tuning, and ultra-wide and ultra-low frequency vibration and noise reduction, as well as providing a new design idea. The novelty of this paper lies in combining Bloch's theorem and finite element method to calculate the band gap, using the transfer function to verify the evaluation; using structural optimization and applying active strain to test the structural tunability; and illustrating the wave propagation and band gap opening mechanism from the vibration mode and energy perspectives. The results show that the structure has excellent vibration and sound insulation effect, with a wide range of band gap opening under active strain.

Summary: The design and analysis of SiC/RGO and GaN/RGO heterojunctions using first-principles hybrid density functional theory reveals that the GaN/RGO heterojunction has better band gap reduction and light absorption capacity compared to the SiC/RGO heterojunction. It also meets the requirements for photocatalytic water splitting, leading to enhanced photocatalytic performance.

Summary: This study presents the deposition of carbon nitride (CNx) films using gas injection magnetron sputtering, with a focus on the transition between different excitation mechanisms of plasma particles and the resulting varied chemical states of the films. The CNx films showed potential for near-infrared devices with high transparency, based on an investigation of the optical band gaps.
