Summary: The deposition of a WO3 thin layer on a p-Si substrate significantly improves the PEC performance of the photoelectrode, leading to increased cathodic photocurrent density and anodic shift in onset potential for water reduction. Variations in oxygen pressures during deposition can modulate the W-O bond covalency and WO6 octahedral structure symmetry, enhancing charge carrier transport and separation. Additionally, manipulation of W-O local atomic structures in the deposited WO3 layer contributes to a significant improvement in PEC performance for solar hydrogen generation.

Summary: This study provides a detailed investigation on the microstructure regulation of SiIP photocathodes. The distribution of micro-pits on SiIPs is found to play a crucial role in determining electrode performance. The microstructural features of SiIPs can be effectively adjusted by controlling the etchant composition and introducing alkali post-treatment. By optimizing the hydrogen evolution reaction (HER) activity and constructing reliable heterojunctions, the performance of SiIP photocathodes can be significantly enhanced, offering new opportunities for unbiased overall water splitting.

Summary: The study found that Fe8Ce2 is the most active photocatalyst, both in standalone powder form and attached on vermiculite, for hydrogen production via water splitting. The photocatalytic activity of Fe2O3/CeO2 photocatalysts is controlled by intrinsic photocatalytic properties of the oxides and the specific surface area of the composite. The formation of heterojunction Type I with bent bands effectively inhibits the recombination of photogenerated charge carriers.

Summary: A p-type heterojunction photoelectrode made of CuAlO2 and CuBi2O4 was developed for the first time by using a solution-based deposition method. Its advantageous bandgap size and favorable band positions make it a highly prospective option for photoelectrochemical water splitting. The heterojunction photoelectrode showed improved photoelectrochemical activity compared to CuBi2O4 alone, attributed to decreased recombination of photo-generated electrons and holes and improved charge separation and transport in the heterostructure.

Summary: Recent progress in the Valley Hall insulator has shown nontrivial topology due to distinct valley index in 2D semiconductor systems. This study proposes a highly tunable topological phase transition using valley photonic crystals, achieved by breaking the inversion symmetry through refractive index changes in optical phase change material (OPCM) in a honeycomb lattice structure. Simulations demonstrate topological protection through light propagation at sharp corners and pseudo-spin photon coupling. Compared to other reconfigurable topological photonics, the proposed scheme offers wider bandwidth and greater tunability in both central bandgap frequency and topological phase transition. The platform holds great potential for practical applications in lasing, light sensing, and high-contrast tunable optical filters.

Summary: A single-shot quantitative amplitude and phase imaging (QAPI) method is proposed by inserting a pair of all-dielectric geometric phase metasurfaces into a traditional microscope. The metasurface pair splits a linearly polarized incident beam into two circularly polarized components and deflects them back toward their initial directions. The interference of the laterally displaced replicas of the input object formed by the metasurface pair generates a retardance image, from which the amplitude and phase information of the object can be reconstructed using a polarized camera.
