Such transport can give proton-based batteries exceptional rate capability and low-temperature operation beyond other working ions. Here we show that in phosphoric acid (H3PO4) electrolytes, vehicular and structural proton transport coexist, and their contributions to conductivity can be quantitatively distinguished. We link structural diffusion directly to hydrogen-bond strength, enabling the precise tuning of proton migration. Guided by this, we reveal a double conductivity peak from regulated structural diffusion. The optimal electrolyte (5.8-M H3PO4) achieves high overall (232.9 mS cm-1) and structural (164.9 mS cm-1) conductivity. A MoO3‖CuFe-TBA battery with this electrolyte outperforms a deep-eutectic benchmark (8.3-M H3PO4), delivering >17,474 W kg-1 at room temperature and retaining 15.1 Wh kg-1 at -75 °C. These findings provide a framework for designing advanced protic electrolytes across electrochemical systems.","PeriodicalId":19058,"journal":{"name":"Nature Materials","volume":"69 1","pages":""},"PeriodicalIF":41.2,"publicationDate":"2025-10-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145215938","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}

Here we extend moiré engineering from artificially assembled thin flakes with mismatched lattice parameters to materials that host incommensurate orders, presenting a long-period moiré superlattice in a layered charge-density-wave compound, EuTe4. Using high-momentum-resolution X-ray diffraction, we found two coexisting incommensurate charge density waves with slightly mismatched in-plane wavevectors. The interaction between these two charge density waves leads to joint commensuration with the lattice and a moiré superstructure with a period of ~13.6 nm, offering key insights into the unique properties of EuTe4, such as the temperature-invariant incommensurate wavevectors and unconventional in-gap states. Owing to interlayer phase shifts, the moiré superstructure exhibits a clear thermal hysteresis, accounting for the large hysteresis in electrical resistivity and numerous metastable states. Our findings open new directions for moiré engineering based on incommensurate lattices and highlight the important role of interlayer ordering in stacked structures.","PeriodicalId":19058,"journal":{"name":"Nature Materials","volume":" ","pages":""},"PeriodicalIF":38.5,"publicationDate":"2025-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145206983","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}

For phase-change materials, the resultant temporal change in electrical resistance seriously hampers neuromorphic computing applications. Here we report an ab-initio-calculation-informed design of amorphous phase-change materials composed of robust 'molecule-like' motifs, depriving the amorphous alloy of critical structural ingredients responsible for relaxation and, hence, resistance drift. We demonstrate amorphous CrTe3 thin films that display practically no resistance drift at any working temperature from -200 °C to 165 °C, and highlight the multilevel encoding ability via a hybrid opto-electronic approach. We further reveal that the same no-drift behaviour holds for melt-quenched amorphous CrTe3 in electronic devices. Moreover, the application potential of CrTe3 is testified by its incorporation in a vehicle with an automatic path-tracking function. Our work provides an alternative route to achieve requisite properties for potential phase-change neuromorphic computing via the judicious design of disordered phase-change materials.","PeriodicalId":19058,"journal":{"name":"Nature Materials","volume":"100 1","pages":""},"PeriodicalIF":41.2,"publicationDate":"2025-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145203479","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}

Here we report that when TTMs are in contact, photoexcitation generates TTM anion-TTM cation pairs. These can decay radiatively or be fully separated under an electric field bias. We use a triphenyl-substituted TTM (P3TTM) in which the phenyl end groups enhance intermolecular interactions. In dilute (5 wt%) films in a wide-energy-gap organic semiconductor host, we observe prompt photoluminescence from the excited radical at 645 nm, and a delayed component, beyond 1 μs, at 800 nm due to recombination of P3TTM anion-cation pairs. Measurements of photocurrent made with diode structures with 100% P3TTM showed close-to-unity charge collection efficiency in reverse bias. We have found 'homojunction' intermolecular charge separation, made possible when the extra energy for double occupancy of the non-bonding radical level on the anion is lower than the energy of the doublet exciton. This opens possibilities for light harvesting using single-material molecular semiconductors.","PeriodicalId":19058,"journal":{"name":"Nature Materials","volume":"17 1","pages":""},"PeriodicalIF":41.2,"publicationDate":"2025-09-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145194606","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}

While phenyl-C61-butyric acid methyl ester (PCBM) is a promising electron-selective material in inverted perovskite solar cells, its dimerization under environmental stress accelerates the material degradation and complicates producing high-quality PCBM layers, thereby compromising device long-term operational stability and scale-up fabrication. Here we investigated the PCBM molecular stacking on perovskite surfaces, finding that the variability in perovskite surface termination leads to orientation and distribution heterogeneity of the PCBM layer, resulting in undesirable dimerization. To address this, we developed a molecular dopant for suppressing PCBM dimer formation, achieving a certified efficiency of 26.4% in laboratory-scale devices and 25.3% in 1 cm2 devices. Furthermore, these devices maintained 93% of their initial power conversion efficiency after 1,500 h of ageing at 85 °C following the ISOS L-2I protocol.","PeriodicalId":19058,"journal":{"name":"Nature Materials","volume":"99 1","pages":""},"PeriodicalIF":41.2,"publicationDate":"2025-09-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145194623","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, existing strategies that rely on frequency- and temperature-dependent dynamics have had limited success in enhancing strain response under such conditions. Here, through promoted local strain fluctuation, we achieve an interlocked polar configuration in spin-coated epitaxial (K,Na)NbO3-based ferroelectric films. The films demonstrate high-frequency strains exceeding 1.1% with high linearity and stability even when measured at 105 Hz. The presence of interlocked monoclinic and tetragonal polar nanoregions boosts piezoelectric response by promoting polarization dynamics across a broad frequency range. Additionally, the interplay between two distinct polarization switching mechanisms, arising from different symmetries and boundary conditions, mutually compensates, contributing to the observed overall linearity. This approach presents a promising yet facile strategy for achieving ferroelectric films with reliable, large and linear strain across a wide high-frequency range.","PeriodicalId":19058,"journal":{"name":"Nature Materials","volume":"24 1","pages":""},"PeriodicalIF":41.2,"publicationDate":"2025-09-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145189100","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, these textures remain largely dependent on the given heterostructures with engineered neighbouring layers to balance the competing energies. Here we report high-density polarization bubbles in van der Waals ferroelectric crystals CuInP2S6, without the need for a spatially confined heterostructure. From piezoresponse force microscopy, it is observed that the formation and distribution of bubble domains exist in the inherent coexistence of polar phases. Crucially, the phase ratio can be facilely tailored by external stimuli such as mechanical force, enabling the labyrinth domains to be manipulated into high-density isolated bubbles through a mechanism involving polar phase competition and flexoelectricity, as revealed through density functional theory and phase-field modelling.
