Summary: Flexible and stable piezoelectric energy harvesters were successfully fabricated using polydimethylsiloxane-embedded m-axis GaN/Al2O3 core-shell nanowires transferred to indium-deposited flexible substrates. Optimizing the piezoelectric performance by controlling the Al2O3 shell thickness showed that a 6 nm thickness exhibited the maximum performance, with performance decreasing when the thickness was increased or decreased. The PEHs were effective in harvesting mechanical energy, even from static strain, and also demonstrated energy supply capabilities for operating a light emitting diode.

Summary: Solar-driven water splitting is a promising way to obtain clean H-2 energy, and the photoelectrochemical approach has attracted significant interest. The oxygen evolution reaction is seen as the stage that limits performance in this technology, highlighting the need for innovative anode materials. Metal oxide semiconductors are relevant in this respect due to their cost-effectiveness and widespread availability. In this study, a combination of chemical vapor deposition and atomic layer deposition was used to synthesize randomly oriented CNT-ZnO core-shell nanostructures, forming a porous coating that adheres well. Compared to directly coated ZnO on Si, the porous structure allows for a larger interface area with the electrolyte, resulting in a 458% increase in photocurrent density under simulated solar light. The photoelectrochemical characterization attributes this performance enhancement to the effective electron withdrawal along the carbon nanotubes (CNTs), leading to a decrease in the onset potential. As for durability, the CNT-ZnO core-shell structure exhibits enhanced photo-corrosion stability for 8 hours under illumination and with a voltage bias.

Summary: With the development of wearable electronics, the demand for high-performance photodetectors with smaller size, lower power consumption, and higher sensitivity has increased. Photodetectors based on one-dimensional zinc oxide nanowires have been intensively investigated, but they can only detect ultraviolet light. This paper reports a heterojunction photodetector based on ZnO/CuO/NiO core-shell-shell nanowires, which shows a fast response and a large sensitivity under UV irradiation. The results indicate that core-shell-shell heterojunction nanostructures can be used to develop high-performance photodetectors for UV-vis broadband photosensing applications.

Summary: Polarizers are commonly used components in optoelectronic devices, but controlling light polarization is still a challenge. Organometal halide perovskites (OMHP) have become the preferred material in photovoltaics and optoelectronics due to their tunable optical properties and excellent light emission. Nanowires and nanorods are key players in controlling light polarization. Highly aligned and anisotropic methylammonium lead iodide perovskite nanowalls fabricated by glancing-angle deposition exhibit anisotropic optical properties and can be used in photovoltaic devices with polarization-sensitive response.

Summary: By using an adamantane plasma polymer pinning layer, we achieve unprecedented crystal strains of 2.8% in monolayer molybdenum disulfide. The strain gauge factors for the A and B excitons of monolayer MoS2 are reported as -99.5 meV/% and -63.5 meV/%, respectively, with a 50 nm adamantane capping layer. Photoluminescence and Raman measurements on the same samples confirm these results. Overall, our study demonstrates that adamantane polymer is an exceptional capping layer for transferring substrate-induced strain to a 2D layer and achieving higher levels of crystal strain.
