Here, a room-temperature 2D layered ferroelectric semiconductor, bismuth oxychalcogenides (Bi2O2Se), is investigated with a thickness down to 7.3 nm (≈12 layers) and piezoelectric coefficient (d33) of 4.4 ±0.1 pm V−1. The random orientations and electrically dependent polarization of the dipoles in Bi2O2Se are separately uncovered owing to the structural symmetry-breaking at room temperature. Specifically, the interplay between ferroelectricity and semiconducting characteristics of Bi2O2Se is explored on device-level operation, revealing the hysteresis behavior and memory window (MW) formation. Leveraging the ferroelectric polarization originating from
Bi2O2Se, the fabricated device exhibits “smart” photoresponse tunability and excellent electronic characteristics, e.g., a high on/off current ratio > 104 and a large MW to the sweeping range of 47% at VGS = ±5 V. These results demonstrate the synergistic combination of ferroelectricity with semiconducting characteristics in Bi2O2Se, laying the foundation for integrating sensing, logic, and memory functions into a single material system that can overcome the bottlenecks in von Neumann architecture.. |

Herein, the synthesis of 2D SnS nanosheets with tailored interlayer spacing is reported, including both expansion and compression, through the active diatomic Pt-Ce pairs. Taking together the experimental results, in situ Raman spectra, and DFT calculations, it is found that the compressed interlayer spacing can tune the electron density of localized p-orbital in Sn into its delocalized states, thus enhancing the chemical affinity towards NO3− and NO2− but inhibiting hydrogen generation simultaneously. This phenomenon significantly facilitates the rate-determining step (*NO3→*NO2) in eNO3RR, and realizes an excellent Faradaic efficiency (94.12%) and yield rate (0.3056 mmol cm−2 h−1) for NH3 at −0.5 V versus RHE. This work provides a powerful strategy for tailoring flexible interlayer spacing of 2D materials and opens a new avenue for constructing high-performance catalysts for ammonia synthesis.. |

Here, we first design a hierarchical Co@NCNT/CoMoOx precatalyst constituted by defective CoMoOx nanosheets grafted with flexible Co@NCNT arrays, followed by a delicate anodic treatment for fast dissolution balance. Benefiting from the multi-level Co@NCNT arrays as a stable micro-environment, the resultant Co@NCNT/CoMoyOx displays excellent electrocatalytic activity with a low overpotential of 195 mV at −100 mA cm−2 and stable 600 h operation for the HER in alkaline media, including natural seawater, which is better than most reported carbon/transition metal-based catalysts. In situ Raman analyses disclose a local high-resolution self-reconstruction evolution of localized Mo species at controllable negative potentials. Density functional theory calculations further demonstrate that the ultimate Mo–Mo surface state accelerates reaction kinetics to promote H2 generation in alkaline media. Our findings provide a unique insight into the mechanism of the structural evolution in the alkaline HER process to pave a new avenue guiding the design of durable and efficient catalysts.. |

Here, the poly(vinylidene fluoride-trifluoroethylene) (P(VDF-TrFE)) wrapped InGaAs nanowire (NW) artificial synapses capable to operate with record-low subfemtojoule power consumption are presented. The essential synaptic behaviors are mimicked and modulated effectively by adjusting the thickness of top P(VDF-TrFE) films. Moreover, the long-term depression is realized by applying visible light (450 nm) because of the negative photoconductivity of InGaAs nanowires. Combined with optimal P(VDF-TrFE) films, the synaptic devices have the more linear long-term potentiation/depression characteristics and the faster supervised learning process simulated by hardware neural networks. The Pavlovian conditioning is also performed by combining electrical and infrared stimuli. Evidently, these ultralow-operating-power synapses are demonstrated with the brain-like behaviors, effective function modulation, and more importantly, the synergistic photoelectric modulation, which illustrates the promising potentials for neuromorphic computing systems.. |

In particular, materials with low dimensionalities (i.e., 0D, 1D, and 2D) possess an extremely large surface area-to-volume ratio to expose abundant active sites for interactions with molecular analytes. Gas sensors based on these materials exhibit a sensitive response to subtle external perturbations on sensing channel materials via electrical transduction, demonstrating a fast response/recovery, specific selectivity, and remarkable stability. Herein, we comprehensively elaborate gas sensing performances in the field of sensitive detection of hazardous gases with diverse low-dimensional sensing materials and their hybrid combinations. We will first introduce the common configurations of gas sensing devices and underlying transduction principles. Then, the main performance parameters of gas sensing devices and subsequently the main underlying sensing mechanisms governing their detection operation process are outlined and described. Importantly, we also elaborate the compositional and structural characteristics of various low-dimensional sensing materials, exemplified by the corresponding sensing systems. Finally, our perspectives on the challenges and opportunities confronting the development and future applications of low-dimensional materials for high-performance gas sensing are also presented. The aim is to provide further insights into the material design of different nanostructures and to establish relevant design guidelines to facilitate the device performance enhancement of nanomaterial based gas sensors.. |

Ho, Artificial visual systems enabled by quasi–two-dimensional electron gases in oxide superlattice nanowires, SCIENCE ADVANCES, 6, eabc6389, 2020.11, Rapid development of artificial intelligence techniques ignites the emerging demand on accurate perception
and understanding of optical signals from external environments via brain-like visual systems. Here, enabled by
quasi–two-dimensional electron gases (quasi-2DEGs) in InGaO3(ZnO)3 superlattice nanowires (NWs), an artificial
visual system was built to mimic the human ones. This system is based on an unreported device concept
combining coexistence of oxygen adsorption-desorption kinetics on NW surface and strong carrier quantumconfinement effects in superlattice core, to resemble the biological Ca2+ ion flux and neurotransmitter release
dynamics. Given outstanding mobility and sensitivity of superlattice NWs, an ultralow energy consumption down
to subfemtojoule per synaptic event is realized in quasi-2DEG synapses, which rivals that of biological synapses
and now available synapse-inspired electronics. A flexible quasi-2DEG artificial visual system is demonstrated to
simultaneously perform high-performance light detection, brain-like information processing, nonvolatile charge
retention, in situ multibit-level memory, orientation selectivity, and image memorizing.. |
