Summary: We have discovered that the complex ferroelectric response of layered materials towards interlayer sliding is determined by the interlayer lattice registry. The entire sliding polarization landscape of two-dimensional layered material interfaces can be described using the polarization registry index (PRI), a simple geometric measure that quantifies the degree of interlayer commensurability. This tool not only aids in understanding the fundamental origin of 2D ferroelectricity, but also allows for efficient characterization and rationalization of existing experimental and computational evidence, as well as prediction of emergent controllable polarization in new noncentrosymmetric layered systems.

Summary: This study presents an effective fabrication strategy for the amorphous ZnGa2O4/NiO heterojunction self-powered ultraviolet (UV) photodetector, considering both low-temperature and band alignment issues. The device demonstrates excellent photovoltaic effect, with ultralow dark current, satisfactory response sensitivity, high detectivity, and fast response speed. Compared to previous UV photodetectors, the proposed device exhibits high responsivity and excellent detectivity, indicating its ability to detect weak signals. The remarkable photoelectric detection capability is attributed to the strong absorption of UV light by amorphous ZnGa2O4 and type-II band alignment at the heterojunctions. Additionally, the photodetector maintains stable functioning without degradation even after two months without external power supply. This work provides a valuable reference for high-performance ZnGa2O4-based UV photodetectors and opens up possibilities for practical industrial production and flexible applications.

Summary: Narrow-bandgap Sn-Pb mixed perovskite single crystals show great potential as photoactive materials for efficient and low-cost near-infrared (NIR) photodetectors. However, the phase separation issue during crystallization process leads to the degradation of optical and electronic properties. In this study, a low-temperature space-confined technique (LT-SCT) is proposed to reduce the crystallization velocities and create pure-phase (FASnI(3))(0.1)(MAPbI(3))(0.9) single crystals. These crystals exhibit excellent crystallinity, high hole mobility, and low surface trap density, enabling their application in self-powered NIR photodetectors with outstanding performance. The work contributes to the development of Sn-Pb mixed perovskite single crystals and offers a promising candidate for efficient and low-cost NIR photodetection.

Summary: Clusters of tightly coupled machinery units can exhibit collective behavior and behave like metamaterials to address environmental disturbances. This is particularly important for harnessing water wave energy, a promising clean energy source with huge reserves but a formidable challenge for traditional generators. In this study, a novel three-dimensional chiral network of triboelectric nanogenerators (TENGs) is designed to effectively harvest water wave energy. The network, unlike bulky and rigid machines, features a distributed architecture with chiral connections between unbalanced units, providing flexibility, hyper-elasticity, and wave absorption behavior similar to mechanical chiral metamaterials. The network can be configured to harvest wave energy in all directions at different scales and depths. An integrated energy harvesting system, combined with a power management circuit, enhances the stored energy by approximately 319 times. This study demonstrates the great potential of the novel 3D chiral network for blue energy harvesting and self-powered systems based on TENGs, which can adapt better to harsh ocean environments with flexible and distributed characteristics. It also presents a paradigm shift from mechanical metamaterial designs to energy harvesting networks, inspiring innovative energy harvesting systems and strongly coupled machinery systems based on metamaterials.
