Unlike optoelectronic devices, lattice distortion driven by A-site cation variation (A = Cs, Rb, K) is a key mechanism for enhancing the switching properties of APbI₃-based flexible memristor devices. This distortion, particularly noticeable in KPbI₃’s orthorhombic phase, alters crystal structure, electronic as well as charge transport properties. Density functional theory (DFT) calculations are performed to calculate ionic migration barriers in the orthorhombic structures, while X-ray photoelectron spectroscopy (XPS) analysis provides insights into the chemical environment and bonding states. Leveraging this effect, KPbI₃ exhibits exceptional non-volatile data storage performance, with a high ON/OFF ratio (∼10³) and self-rectification (∼10³). Conversely, CsPbI₃ with subtle lattice distortion, displays superior synaptic behavior and efficient spike-timing-dependent plasticity (STDP), ideal for neuromorphic computing. CsPbI₃ demonstrates remarkable potential for artificial neural networks (ANNs), achieving ∼97 % accuracy in Modified National Institute of Standards and Technology (MNIST) dataset, image classification with minimal training, and 85 % accuracy in convolutional neural networks (CNNs) on the <strong>Canadian Institute for Advanced Research (</strong>CIFAR-10) dataset. Our findings highlight the critical role of small cation size in modulating Schottky barriers, morphology, and ionic migration, and their direct impact on resistive switching properties. These results underscore the potential of cation size modulation as an effective strategy for designing memristors for a wide range of applications, including neuromorphic computing, signal processing, logic gates, and quantum computing.</div></div>","PeriodicalId":394,"journal":{"name":"Nano Energy","volume":"138 ","pages":"Article 110871"},"PeriodicalIF":16.8,"publicationDate":"2025-03-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143640140","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}

The laser-induced high-entropy spherical LB becomes convenient supports for hosting well-dispersed Pt species. Owing to the atomic rearrangement caused by the high-energy laser irradiation, strong physicochemical interactions between Pt species and LB are confirmed with the formation of Pt-O and Pt-Fe bonds. The tight cohesion endows Pt/LB faster charge-transfer rate and higher turnover frequency during HER. In both alkaline and acidic media, the Pt/LB catalyst possesses a near-zero onset overpotential and a low Tafel slope, superior to most Pt catalysts loaded on other supports. It is theoretically verified that Pt-Fe or Pt-O coordination can result in a smaller reaction barrier and a shorter diffusion time than pure Pt, thereby improving the catalytic activity of HER.

Rotary TENG can harvest energy in the form of water energy, wind energy, and so on. However, almost all of the rotary TENGs reported so far are solid-solid contacts. The solid-solid TENG is prone to friction loss during operation, which results in the service life and stability not being adequately guaranteed. In this paper, a rotary solid-liquid TENG (RSL-TENG) is proposed to solve the above problems. The results show that RSL-TENG has high stability after up to 50 h of continuous 600,000 cycles of operation with no decay of the transferred charge after 50 h. The charge density of RSL-TENG is as high as 52.5 μC/m² when using fluorinated ethylene propylene (FEP) film and 80 mL of purified water.
