Optoelectronic memristive devices that enable neuromorphic sensory computing with integrated sensing, memory and processing functionalities, have been identified as a promising element for next-generation artificial vision systems. However, the optoelectronic memristive dynamics of these devices are largely based on engineered structures and/or innovative functional nanomaterials, presenting critical challenges for their silicon complementary metal-oxide-semiconductor (CMOS) technology compatibility at a scalable application perspective. Here we demonstrate a CMOS-compatible optoelectronic memristive device based on the aluminium scandium nitride (AlScN) ferroelectric/two-dimensional (2D) semiconductor heterostructure enabled ferroelectric field-effect transistor (FeFET). We show that such FeFETs can be fabricated under the back-end-of-line (BEOL) thermal budget and exhibit non-volatile electronic memory properties. Harnessing the light-induced ferroelectric domain reconfiguration in the AlScN layer, these devices offer light-tunable short- and long-term memristive properties, directly linking light stimulation history to electronic dynamics. Such a working principle enables rich optoelectronic synaptic functions and the implementation of the psychological human visual memory model, offering a critical demonstration for optical neuromorphic sensory computing. Furthermore, a linear and non-volatile dependence of the photoresponse current on the light intensity is exploited for the optical information decoding. Our results mark new opportunities for CMOS-compatible optoelectronic memristive devices as the hardware basis of next-generation neuromorphic vision architectures.

光电记忆器件能够实现集成传感、记忆和处理功能的神经形态感觉计算，已被确定为下一代人工视觉系统中有前途的元件。然而，这些器件的光电忆阻动力学主要基于工程结构和/或创新的功能纳米材料，从可扩展的应用角度来看，它们的硅互补金属氧化物半导体（CMOS）技术兼容性面临着严峻的挑战。在这里，我们展示了一种基于氮化铝钪（AlScN）铁电/二维（2D）半导体异质结构使能铁电场效应晶体管（FeFET）的cmos兼容光电忆阻器件。我们证明这种效应场效应管可以在后端线（BEOL）热预算下制造，并具有非易失性电子存储特性。利用AlScN层中光诱导的铁电畴重构，这些器件提供了光可调的短期和长期记忆电阻特性，直接将光刺激历史与电子动力学联系起来。这种工作原理使丰富的光电突触功能和人类心理视觉记忆模型得以实现，为光学神经形态感觉计算提供了重要的论证。此外，光响应电流和光强的线性和非易失性依赖关系被用于光学信息解码。我们的研究结果标志着cmos兼容光电记忆器件作为下一代神经形态视觉架构硬件基础的新机遇。

The high non-radiative recombination caused by lattice defects and photoinduced phase segregation remains a major challenge hindering the development of wide-bandgap perovskite solar cells (PSCs), severely impairing their open-circuit voltage (V_OC), efficiency, and long-term stability. Herein, we propose a co-passivation strategy to address lattice defects associated with Br-I ions in 1.7 eV bandgap Cs_0.22FA_0.78PbI_2.25Br_0.75 perovskite material. This approach effectively suppresses surface defects and reduces the non-radiative recombination rate of the perovskite material, increasing the V_OC from 1.13 V to a record 1.29 V. Based on this strategy, we achieved a record-breaking efficiency of exceeding 23% for wide-bandgap PSCs. The unencapsulated devices retained 98.5% of their initial efficiency after more than 2000 h of testing at room temperature and maintained over 80% efficiency after 900 h at 85 °C. These significant improvements in both efficiency and stability are attributed to targeted passivation against the uneven nucleation unique to wide-bandgap perovskite. By introducing iodine-rich passivators, the imbalanced Br and I distribution in the film was balanced, which provides a promising pathway for enhancing the performance of mixed-halide perovskite materials.

由晶格缺陷和光致相偏析引起的高非辐射复合仍然是阻碍宽禁带钙钛矿太阳能电池（PSCs）发展的主要挑战，严重损害了它们的开路电压（VOC）、效率和长期稳定性。在此，我们提出了一种共钝化策略来解决1.7 eV带隙Cs0.22FA0.78PbI2.25Br0.75钙钛矿材料中与Br-I离子相关的晶格缺陷。这种方法有效地抑制了表面缺陷，降低了钙钛矿材料的非辐射复合率，将VOC从1.13 V提高到创纪录的1.29 V。基于这一策略，我们在宽带隙psc上实现了超过23%的破纪录效率。在室温下测试超过2000小时后，未封装的器件保持了98.5%的初始效率，在85℃下测试900小时后保持了80%以上的效率。这些效率和稳定性的显著提高归功于针对宽带隙钙钛矿特有的不均匀成核的靶向钝化。通过引入富碘钝化剂，平衡了薄膜中不平衡的Br和I分布，为提高混合卤化物钙钛矿材料的性能提供了一条有希望的途径。

Upon the arrival of H. sapiens in Europe, the abundance and diversity of the mammalian carnivore community progressively diminished. The factors contributing to this increased human pressure and its potential association with Neanderthal extinction remain unknown. This study identifies biotic and abiotic effects on the structure and assembly of the carnivore community at the European scale during Marine Isotope Stage 3 by integrating analyses of their geographic ranges, co-occurrence patterns, and generalized mixed models. Results show that during the replacement of Neanderthals by Homo sapiens, the ranges of carnivores and omnivores contracted and their co-occurrence frequency increased, leading to new intra-guild interaction dynamics. Additionally, H. sapiens occupied a larger portion of the carnivore community’s fundamental niche. Climate change, the demographic decline of keystone species, and the broader niche breadth of H. sapiens reduced the interconnectivity of the co-occurrence network within the mammalian carnivore community, shaping novel dynamics of human-carnivore interactions in Europe.

智人到达欧洲后，哺乳动物食肉动物群落的丰富度和多样性逐渐减少。导致这种人类压力增加的因素及其与尼安德特人灭绝的潜在联系尚不清楚。本研究通过对海洋同位素阶段3的地理范围、共现模式和广义混合模型的综合分析，确定了生物和非生物对欧洲尺度食肉动物群落结构和组合的影响。结果表明，在智人取代尼安德特人的过程中，食肉动物和杂食动物的活动范围缩小，共存频率增加，导致了新的种群内互动动态。此外，智人占据了食肉动物群落基本生态位的更大一部分。气候变化、关键物种数量的减少以及智人生态位的扩大，降低了哺乳动物食肉动物群落内共生网络的互联性，形成了欧洲人类与食肉动物相互作用的新动态。

With a high capacity at low cost, manganese oxides utilizing oxygen redox chemistry are desirable candidates for replacing nickel- and cobalt-based cathodes. However, they suffer from rapid oxygen activity fading, commonly related to bonding interactions between the transition metals and oxygen, while receiving limited attention on the role of Li ions. Here, we demonstrated the protective role of Li ions in maintaining oxygen orbital symmetry to improve oxygen redox reversibility. The orbital symmetry breaking induced by Li ion migration leads to a disproportionation of oxygen during charging. This results in some oxygen becoming overoxidized and labile, compromising the structure and cycling stability. This mechanism is validated through experiments on P3-Na_0.6Li_0.2Mn_0.8O₂ and other layered manganese-based cathodes, as well via dynamic simulations. Finally, employing P2-Na_0.75Li_0.25Mn_0.75O₂, we propose a design strategy for stabilizing Li ions via electrostatic field disordering, enhancing the capacity retention over 150 cycles from 46% to 72%. The insights open an avenue towards the rational design of high-performance manganese-based cathodes.

利用氧氧化还原化学制备的锰氧化物具有高容量、低成本的优点，是取代镍基和钴基阴极的理想候选材料。然而，它们的氧活性会迅速下降，这通常与过渡金属与氧之间的键相互作用有关，而锂离子的作用受到的关注有限。在这里，我们证明了锂离子在维持氧轨道对称以提高氧氧化还原可逆性方面的保护作用。锂离子迁移引起的轨道对称破缺导致了充电过程中氧的歧化。这导致一些氧变得过度氧化和不稳定，损害结构和循环稳定性。通过在P3-Na0.6Li0.2Mn0.8O2等层状锰基阴极上的实验和动态模拟验证了该机理。最后，采用P2-Na0.75Li0.25Mn0.75O2，我们提出了一种通过静电场无序来稳定Li离子的设计策略，将150次循环后的容量保持率从46%提高到72%。这些见解为高性能锰基阴极的合理设计开辟了一条道路。

Precise tuning of the localized electronic structure in transition metal oxides is key to advancing functional materials, yet conventional chemical methods often introduce un-neat side effects that impede control and complicate mechanistic studies. We propose a neat strategy that uses facile and versatile quenching-induced lattice tensile strain to adjust d–p orbital hybridization in metal–oxygen (M–O) bonds. Studies show that tensile strain boosts Mn 3d and O 2p orbital overlap, lowers Mn 3d energy levels, and enhances their splitting, increasing electron displacement-induced polarization loss. This significantly improves the microwave absorption of oxides, a top candidate for microwave absorbents currently limited by poor absorption performance. The strain-modified Mn_2.05Co_0.91O₄ achieves superior performance: a 7.52 GHz bandwidth (1.93 times that of zero-strain) and a minimum reflection loss of −67.47 dB. This approach’s versatility is confirmed in perovskites, where strained samples exhibit 1.83 times the bandwidth of unstrained ones. This study connects lattice strain to electronic structure modulation for microwave absorbers, spintronics, catalysis, and semiconductors.

精确调整过渡金属氧化物中的局部电子结构是推进功能材料的关键，然而传统的化学方法经常引入不整洁的副作用，阻碍了控制并使机理研究复杂化。我们提出了一种巧妙的策略，使用简单和通用的淬火诱导晶格拉伸应变来调整金属-氧（M-O）键中的d-p轨道杂化。研究表明，拉伸应变增加了Mn 3d和o2p轨道重叠，降低了Mn 3d能级，增强了它们的分裂，增加了电子位移引起的极化损失。这大大提高了氧化物的微波吸收，氧化物是目前受吸收性能差限制的微波吸收剂的首选。应变修正后的mn2.05 co0.9104具有优异的性能：7.52 GHz带宽（是零应变的1.93倍），最小反射损耗为-67.47 dB。这种方法的多功能性在钙钛矿中得到了证实，其中应变样品的带宽是未应变样品的1.83倍。本研究将晶格应变与微波吸收体、自旋电子学、催化和半导体的电子结构调制联系起来。
