Summary: This study presents a defect analysis in Cd and Te inclusion regions within Bridgman-grown Cd0.95Mn0.05Te crystals for nuclear detectors. Contrary to Cd inclusions causing microcracks, Te inclusions do not generate defects but induce higher stresses. The higher stress from Te inclusions has a smaller impact on charge carrier transport in detectors compared to Cd inclusions, as confirmed by mu tau product measurements.

Summary: This study successfully fabricated well-aligned WO3 snowflake-like hierarchical arrays with (020) facet perpendicular to the FTO substrate. The fabricated samples were characterized by XRD, SEM, and UV-vis. The SHA photoanode exhibited an impressive photocurrent density of 2.43 mA·cm^-2 at 1.23 V vs RHE, which is 1.76 times higher than the sandwich-like structures. This improved performance can be attributed to the special SHAs and the preferred orientation, which would effectively promote the separation and transfer of carriers.

Summary: Improving the crystal quality of AlGaN can be achieved by pretreating the sapphire substrate with Al-ion implantation. The results show that the screw and edge dislocation densities of AlGaN grown on the Al-ion implanted sapphire substrate are reduced. At an Al-ion dose of 1 x 1012 cm-2, the screw and edge dislocation densities are significantly reduced. The photoluminescence spectra also indicate enhanced optical performance. This innovative method can effectively reduce the dislocation density of AlGaN epilayers and can be applied to other substrates for AlGaN epitaxy.

Summary: This study presents a simple and template-less technique for growing ultra-long cadmium oxide nanowires on an ITO surface from an aqueous solution. The diameter of the nanowires ranges from 10 to 30 nm with lengths up to a few tens of micrometers. The concentration of solution precursors is crucial for the growth density of the nanowires on the surface, while structural growth (length and geometry) is less affected by precursor concentration. These nanowires may have unique properties for potential use in photonics and optoelectronics materials.

Summary: Black arsenic phosphorus (b-AsP) is a promising material for midwave infrared photodetectors, but the lack of high-quality crystal synthesis strategy and susceptibility to oxidation are obstacles. In this study, a stable strategy for synthesizing highly oriented b-AsP crystals was proposed, achieving superior crystal quality with low oxygen content on the surface. Additionally, the characteristics of interlayer synchronous oxidation and surface hydrolysis of b-AsP were revealed for the first time, providing guidance for the synthesis and application of b-AsP materials.

Summary: Through material modification, the commercial polypropylene separator is successfully modified with a cationic covalent organic framework (COF-F@PP), which has abundant nanopores to homogenize the lithium ions flux and can interact with electrolyte solvent molecules to form a desolvation structure of Li+. The F- within the nanopores helps to build a robust LiF-riched solid electrolyte interphase to avoid side reactions between the lithium anode and electrolyte. Therefore, COF-F@PP exhibits excellent cycling stability, high Coulombic efficiency, and superior rate capability in Li//LFP coin cell at 5 C, low N/P ratio (2.19) full cell, and pouch cell at 1 C.

The composite electrode exhibited low overpotential, Tafel slope, icorr, and high voltage stability, outperforming most reported Ti-based PbO2 electrode materials. The excellent catalytic activity can be attributed to the low resistance and porous interlayer of TiH2 nanosheets, as well as the addition of Mn3O4@C micro-flakes to the active layer.
