Central Motif Crystalline lattice structure with a purposeful atomic vacancy (defect site) glowing at its core, representing TiO₂ or g-C₃N₄. Dual energy pathways are released by the defect: Electron(e⁻) trajectory (blue vortex) ascending toward the conduction band (CB). The red vortex, or hole (h⁺) trajectory, is descending toward the valence band (VB). 2.Dynamic Elements: Light Interaction: Sunlight beams striking the defect site and splitting into spectral flares (signaling enhanced light absorption). Charge Separation:streams of e⁻ and h⁺ diverge toward opposing edges, preventing recombination (represented as avoided collision points). Catalytic Reactions: Reduction side: e⁻ stream converting H₂O to blue H₂ bubbles. Oxidation side: pollutants and organic dyes (red) are broken down by the stream. 3. Color Palette Base: Deep cosmic blue (the bulk of a semiconductor) with neon accents (defect energy).-Bands: CB is electric blue (top), and VB is crimson gradient (bottom).-Light effects: Solar excitation produces gold-white radiance.\u0000\u0000 <figure>\u0000 <div><picture>\u0000 <source></source></picture><p></p>\u0000 </div>\u0000 </figure></p>","PeriodicalId":48538,"journal":{"name":"Infomat","volume":"7 9","pages":""},"PeriodicalIF":22.3,"publicationDate":"2025-09-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/inf2.70082","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145181576","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Existing photoeletric memristor are limited by the need for specific wavelengths or long input times to maintain stable behaviour. Here, we introduce a benzothiophene-modified covalent organic framework, enhancing the photoelectric response of methyl trinuclear copper for low-voltage (0.2 V) redox processes. The material enables the modulation of 50 conductive states via light and electrical signals, improving recognition accuracy in low light, dense fog, and high-frequency motion. The ITO/BTT-Cu3/ITO device's accuracy increases from 7.1% with 2 states to 87.1% after training. This construction strategy and the synergistic effect of photoelectric interactions offer a new pathway for the development of photoelectric neuromorphic computing elements capable of processing environmental information in situ.\u0000\u0000 <figure>\u0000 <div><picture>\u0000 <source></source></picture><p></p>\u0000 </div>\u0000 </figure></p>","PeriodicalId":48538,"journal":{"name":"Infomat","volume":"7 9","pages":""},"PeriodicalIF":22.3,"publicationDate":"2025-09-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/inf2.70081","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145181596","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, a limited understanding of how these defects influence photocatalytic properties remains a persistent challenge. This review comprehensively analyzes the vital role of defect engineering for enhancing the photocatalytic performance, highlighting its significant influence on material properties and efficiency. It systematically classifies defect types, including vacancy defects (oxygen and metal vacancies), doping defects (anion and cation), interstitial defects, surface defects (step edges, terraces, kinks, and disordered layers), antisite defects, and interfacial defects in the core–shell structures and heterostructure borders. The impact of complex defect groups and manifold defects on improved photocatalytic performance is also examined. The review emphasizes the principal benefits of defect engineering, including the enhancement of light adsorption, reduction of band gaps, improved charge separation and movements, and suppression of charge recombination. These enhancements lead to a boost in catalytic active sites, optimization of electronic structures, tailored band alignments, and the development of mid-gap states, leading to improved structural stability, photocorrosion resistance, and better reaction selectivity. Furthermore, the most recent improvements, such as oxygen vacancies, nitrogen and sulfur doping, surface defect engineering, and innovations in heterostructures, defect-rich metal–organic frameworks, and defective nanostructures, are examined comprehensively.

However, ETH based on conventional ferroelectrics encounters significant challenges attributed to the surface with dangling bonds and the associated depolarization field. Here, we introduce a novel 2D ETH device based on the anomalous interfacial effect between 2D layered ferroelectric CuCrP₂S₆ and ambipolar WSe₂, creating a versatile platform for nonvolatile memory and high-performance optoelectronic applications. The device capitalizes on the realization of ETH through a localized doping strategy facilitated by ferroelectric polarization-assisted charge trapping. When modulated to a p–n junction diode, the device showcases superior rectifying characteristics and high-performance self-powered photodetection, with a highest responsivity over 0.14 A·W⁻¹. Moreover, the nonvolatile ETH device enables a single device to implement complex optoelectronic logics of exclusive OR (XOR), OR, and not implication (NIMP) that can be reconfigured by light illumination. Compared to the traditional CMOS-based logics, the ETH device significantly reduces the transistor number by 87.5%, 83.3%, and 87.5% for XOR, OR, and NIMP, respectively.

However, the physical separation of sensing, memory, and computational units in traditional biometric systems introduces severe decision latency and operational power consumption. Herein, an in-sensor reservoir computing (RC) system based on MoTe₂/BaTiO₃ optical synapses is proposed to detect and recognize the faces and fingerprints information. In optical operation mode, the device exhibits low energy consumption of 41.2 pJ, long retention time of 3 × 10⁴ s, high endurance of 10⁴ switching cycles, and multifunctional sensing-memory-computing visual simulations. The light intensity-dependent optical sensing and multilevel optical storage properties are exploited to achieve sunburned eye simulation and image memory functions. These nonlinear, multi-state, short-term storage, and long-term memory characteristics make MoTe₂/BaTiO₃ optical synapses a suitable reservoir layer and readout layer, with short-term properties to project complicated input features into high-dimensional output features, and long-term properties to be used as a readout layer, thus further building an in-sensor RC system for face and fingerprint recognition. Under the 40% Gaussian noise environment, the system achieves 91.73% recognition accuracy for face and 97.50% for fingerprint images, and experimental verification is carried out, which shows potential in practical applications. These results provide a strategy for constructing a high-performance in-sensor RC system for high-accuracy biometric identification.</p><p>\u0000 <figure>\u0000 <div><picture>\u0000 <source></source></picture><p></p>\u0000 </div>\u0000 </figure></p>","PeriodicalId":48538,"journal":{"name":"Infomat","volume":"7 8","pages":""},"PeriodicalIF":22.3,"publicationDate":"2025-06-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/inf2.70036","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144905612","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
