Summary: In recent years, advancements in microfabrication and nanofabrication technology have led to significant progress in plasmonic sensor technologies, which can meet the demand for high responsiveness photodetectors. We developed an efficient, scalable, and low-cost near-infrared (NIR) photodetector based on a nanostructured Sb2Se3 film deposited on a p-type micropyramidal Si substrate. Our results demonstrated that the optimized thickness of the Sb2Se3 layer significantly enhanced the responsivity, and the device achieved the highest specific detectivity of 2.25 x 10(15) Jones at a bias voltage of 0.5 V and a power density of 15 mW/cm(2). The field enhancement provided by the Kretschmann configuration of Si pyramids played a crucial role in the enhanced responsivity, making this photodetector suitable for scalable and cost-effective plasmonic-based NIR photodetectors.

Summary: In this study, carbon-coated KVPO4F nanoplates were synthesized using a simple one-step sintering process, where the V-F-C bond generated by fluorinated-polymer-derived carbon at the interface of KVPO4F/C nanoplates reduced F loss and improved the electronic conductivity and ion migration ability of KVPO4F. The as-synthesized KVPO4F/C cathode exhibited excellent capacity and rate capability, and the KVPO4F/C//soft carbon full cell showed a high energy density.

Summary: Metal additive manufacturing (AM) provides unparalleled design freedom for optimized device development, but the use of nonconventional aluminum alloys has made micro/nanostructuring in metal AM challenging. In this study, techniques are developed to investigate the micro/nanostructuring of the most common metal AM material, AlSi10Mg. A surface structuring technique is designed to create unique two-tier nanoscale architectures that show low adhesion, excellent resilience to condensation flooding, and enhanced liquid-vapor phase transition. The study demonstrates that these nanostructures achieve significantly higher heat transfer coefficient compared to conventional condensation methods. The results highlight the potential of AM-enabled nanostructuring for improving droplet confinement and detachment.

Summary: A tailored interface at the buried perovskite heterojunction improved the performance and reliability of n-i-p plane structure perovskite photovoltaic devices by refining interfacial properties. Using phenethylammonium iodide (PEAI) to regulate the SnO2/perovskite interface contributed to higher electronic mobility of ESLs and optimized electron extraction rate. The addition of PEAI also suppressed non-radiative recombination of perovskites and improved the crystallinity of the ESL film, leading to a higher specific detectivity, responsivity, and linear dynamic range for the metal halide perovskite photodetector (PPD) based on PEAI-modified SnO2.

Summary: Polyacrylic acid complexed with polyaniline (PAA/PANI) composite materials have the potential to form organic mixed ion-electron conductive (OMIEC) films, which can be used in optoelectronic and energy storage applications. The composite films are formed through an acid-base reaction, resulting in strong electrostatic interactions and intermolecular hydrogen bonds between PANI and PAA. The separation of PANI-rich domains from PAA-rich matrix in the composite films is observed. The electrical conductivity of the composite films is higher when the content of PANI is 33 wt%, due to the high ionic-electronic coupling at the interface between phase-separated regions.
