However, existing devices typically exhibit narrow spectral response ranges and operate in a single mode (for example, non-volatility), limiting their applications in complex computing scenarios. Here we introduce photonic memristor arrays based on a wafer-scale hexagonal boron nitride (hBN)/silicon (Si) heterostructure. These memristors are developed via in situ, low-temperature (250 °C), large-area growth of highly homogeneous hBN films on Si-based substrates. The devices exhibit opto-reconfigurability across a broad spectral range from ultraviolet to near infrared. By adjusting the incident laser power, the device can be reconfigured between non-resistive-switching, volatile and non-volatile modes. This light-induced reconfigurability is attributed to the formation of conductive filaments through interactions between hydrogen ions and photogenerated electrons within the engineered hBN/Si heterostructures. Furthermore, the photonic memristor features a switching ratio exceeding 109, retention time surpassing 40,000 s, endurance over 106 cycles and thermal stability up to 300 °C. These findings provide a scalable solution for developing integrated sensing–storage–computation artificial vision systems, fully compatible with sophisticated Si-based semiconductor technologies.","PeriodicalId":18915,"journal":{"name":"Nature nanotechnology","volume":"718 1","pages":""},"PeriodicalIF":38.3,"publicationDate":"2025-07-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144747655","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Hexagonal boron nitride (hBN) is particularly attractive for non-volatile resistive-switching devices (that is, memristors) due to its outstanding electronic, mechanical and chemical stability. However, integrating hBN memristors with Si-CMOS electronics faces challenges as it requires either high-temperature synthesis (exceeding thermal budgets) or transfer methods that introduce defects, impacting device performance and reliability. Here we introduce the synthesis of hBN films at CMOS-compatible temperatures (<380 °C) using electron cyclotron resonance plasma-enhanced chemical vapour deposition to realize transfer-free, CMOS-compatible hBN memristors with outstanding electrical characteristics. Our studies indicate a polycrystalline structure with turbostratic features in as-deposited hBN films and good wafer-level uniformity in morphology (size, shape and orientation). We demonstrate a large array of hBN memristors achieving high yield (~90%), stability (endurance, retention and repeatability), programming precision for multistate operation (>16 states) and low-frequency noise performance with minimal random telegraph noise. Furthermore, we directly integrate memristive devices on industrial CMOS test vehicles to demonstrate excellent endurance, achieving millions of programming cycles with a high technology readiness level. This represents an important step towards the wafer-scale CMOS integration of hBN-memristor-based electronics.","PeriodicalId":18915,"journal":{"name":"Nature nanotechnology","volume":"216 1","pages":""},"PeriodicalIF":38.3,"publicationDate":"2025-07-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144747656","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, owing to the volume changes in Li metal electrodes and Li reservoir loss during battery operation, this requirement has not yet been realized in Li metal cells. Here, to overcome these issues, we propose a zero-volume-change, complete-sealing design for a nanoengineered composite material consisting of multilayer reduced graphene oxide and zinc oxide. This composite electrode material can accommodate Li metal without showing negligible volume changes while promoting the formation of an inorganic-rich solid-electrolyte interphase. When the nanoengineered Li/reduced graphene oxide/zinc oxide electrode is tested in combination with a Li metal electrode in a coin cell configuration using non-aqueous electrolyte solutions, Li plating/stripping Coulombic efficiency values ranging from 99.9900% to 99.9999%, for almost 2,000 cycles at a current density of 1 mA cm−2, can be calculated. Testing of the nanoengineered Li/reduced graphene oxide/zinc oxide electrode in combination with high-potential electrodes (for example, LiNi0.8Co0.1Mn0.1O2 or LiFePO4) in non-aqueous coin cell configuration also demonstrates improved performance compared with the high-potential coin cells utilizing pristine Li metal electrodes.","PeriodicalId":18915,"journal":{"name":"Nature nanotechnology","volume":"14 1","pages":""},"PeriodicalIF":38.3,"publicationDate":"2025-07-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144719485","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Herein, we report an industry-compatible disorder-to-disorder synthesis approach to achieve wafer-scale ultraclean MAC (UC-MAC) within a timescale of seconds, featuring optimized ångström polygons without detectable metal contamination, and nanosized pores. In contrast to metal-contaminated MAC, UC-MAC allows atomic-scale characterization of intrinsic electronic properties and functions as an ångström-scale membrane, facilitating the splitting of high-flux H2+ ions into a high-precision proton beam with minimal detrimental fragment-proton scattering events, about half and 40 times less than those from single-crystal graphene and commercial carbon thin films, respectively. The minimum possible membrane material thickness that can yield a highly sharpened proton beam with accurately modulated beam current is desired for proton therapy.","PeriodicalId":18915,"journal":{"name":"Nature nanotechnology","volume":"133 1","pages":""},"PeriodicalIF":38.3,"publicationDate":"2025-07-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144715302","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Current machine vision sensors, including frame-based and event-based types, often fall short due to their limited temporal dynamics compared with the human retina, hindering their overall performance and adaptability. In this work, we present an event-driven retinomorphic photodiode (RPD) that mimics the retina’s layered structure and signal pathway. The RPD achieves this by vertically integrating an organic donor–acceptor heterojunction, an ion reservoir with a porous web-like morphology, and a Schottky junction into a single diode through controlled layer-by-layer fabrication and precise nanostructure modulation. Each component replicates a key retinal process, and their spontaneous interaction results in environment-adaptive dynamics. This design yields a dynamic range exceeding 200 dB, substantially reduces noise and data redundancy, and allows for high-density integration. We demonstrate that these improvements enable high-quality machine vision, even under extreme lighting conditions. Our work demonstrates a bottom-up approach to retinomorphic sensors, propelling the development of robust and responsive machine vision systems adaptable to complex and dynamic lighting environments. A photodiode with bio-plausible event sensing, filtering and adaptation behaviours to replicate the retinal nanostructure and visual pathway is presented, enabling consistent and high-performance machine vision under extreme lighting.","PeriodicalId":18915,"journal":{"name":"Nature nanotechnology","volume":"20 9","pages":"1213-1220"},"PeriodicalIF":34.9,"publicationDate":"2025-07-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144684940","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Spatially indirect interlayer excitons (IXs) exhibit broad tunability of their emission energy via the quantum-confined Stark effect. However, the electrical tunability of IXs has not been exploited in cavity-coupled systems until now. Here we modulate the detuning between the cavity resonance and the IX emission in a monolithic Fabry–Perot cavity using an applied vertical electric field. We reveal a simultaneous enhancement of both the emission intensity and lifetime of weakly coupled IXs when in resonance with the optical cavity owing to strong Purcell inhibition and cavity transparency effects. We further investigate the tunable momentum dispersion of coupled IXs through back-focal-plane imaging and explain our results by the cavity coupling of IX transition dipoles as supported by theoretical modelling. Our work demonstrates an integration effort enabling the versatile tuning of highly interacting IXs within monolithic cavities, revealing the attractiveness of electrically tunable IX cavity coupling for both fundamental studies towards exciton condensate manipulation and future integration of excitonic devices.","PeriodicalId":18915,"journal":{"name":"Nature nanotechnology","volume":"29 1","pages":""},"PeriodicalIF":38.3,"publicationDate":"2025-07-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144645478","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
