However, such modulation has not been emulated in physical devices. Memristors are ideal electrical components for artificial synapses, but up till now they are hardly reported to respond to ultrasound signals. Here we design and fabricate a HfO_<i>x</i>-based memristor on 64°Y-X LiNbO₃ single crystal substrate, and successfully realize artificial synapses modulation by shear-horizontal surface acoustic wave (SH-SAW). It is a prominent short-term resistance modulation, where ultrasound has been shown to cause resistance drop for various resistance states, which could fully recover after the ultrasound is shut off. The physical mechanism illustrates that ultrasound induced polarization potential in the HfO_<i>x</i> dielectric layer acts on the Schottky barrier, leading to the resistance drop. The emulation of neuron firing frequency modulation through ultrasound signals is demonstrated. Moreover, the joint application of ultrasound and electric voltage yields fruitful functionalities, such as the enhancement of resistance window and synaptic plasticity through ultrasound application. All these promising results provide a new strategy for artificial synapses modulation, and also further advance neuromorphic devices toward system applications.</p><p>\u0000 <figure>\u0000 <div><picture>\u0000 <source></source></picture><p></p>\u0000 </div>\u0000 </figure></p>","PeriodicalId":48538,"journal":{"name":"Infomat","volume":"6 6","pages":""},"PeriodicalIF":22.7,"publicationDate":"2024-02-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/inf2.12528","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140001939","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}

In this study, we investigate the influence of commonly used solvents on the quality of the CsSnI₃ films. Remarkably, DMSO exhibits a stronger interaction with SnI₂, forming a stable intermediate phase of SnI₂·3DMSO. This intermediate effectively inhibits the oxidation of Sn²⁺ and slows down the crystallization rate, bringing in lower defect state density and higher photoluminescence quantum yield of the prepared perovskite films. Consequently, the corresponding Pero-LEDs achieve a maximum external quantum efficiency (EQE) of 5.6%, among the most efficient near-infrared Pero-LEDs.

By exploiting the photo-induced photovoltaic and pyroelectric effects of a Schottky junction which is created between BaTiO₃ and LaNiO₃, the device is able to provide five different optoelectronic logic gates, which can be operated using input lasers of different wavelength (405 or 785 nm). The mode of operation of the logic gate can be switched by controlling the wavelength and intensity of the input laser, where the switching process is both lossless and reversible.

However, the short lifespan of PSCs with initial efficiency still blocks their practical applications. This operational instability may originate from the intrinsic and extrinsic degradation of materials or devices. Although the lifetime of PSCs has been prolonged through component, crystal, defect, interface, encapsulation engineering, and so on, the systematic analysis of failure regularity for PSCs from the perspective of materials and devices against multiple operating stressors is indispensable. In this review, we start with elaboration of the predominant degradation pathways and mechanism for PSCs under working stressors. Then the strategies for improving long-term durability with respect to fundamental materials, interface designs, and device encapsulation have been summarized. Meanwhile, the key results have been discussed to understand the limitation of assessing PSCs stability, and the potential applications in indoor photovoltaics and wearable electronics are demonstrated. Finally, promising proposals, encompassing material processing, film formation, interface strengthening, structure designing, and device encapsulation, are provided to improve the operational stability of PSCs and promote their commercialization.</p><p>\u0000 <figure>\u0000 <div><picture>\u0000 <source></source></picture><p></p>\u0000 </div>\u0000 </figure></p>","PeriodicalId":48538,"journal":{"name":"Infomat","volume":"6 4","pages":""},"PeriodicalIF":22.7,"publicationDate":"2024-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/inf2.12522","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139773641","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, the kinetic performance and cyclic stability of cathode materials are limited by the strong interactions between Mg ions and the crystal lattice. Here, we demonstrate the unique Mg²⁺-ion storage mechanism of a hierarchical accordion-like vanadium oxide/carbon heterointerface (V₂O₃@C), where the V₂O₃ crystalline structure is reconstructed into a MgV₃O₇∙H₂O phase through an anodic hydration reaction upon first cycle, for the improved kinetic and cyclic performances. As verified by in situ/ex situ spectroscopic and electrochemical analyses, the fast charge transfer kinetics of the V₂O₃@C cathode were due to the crystal-reconstruction and chemically coupled heterointerface. The V₂O₃@C demonstrated an ultrahigh rate capacity of 130.4 mAh g⁻¹ at 50 000 mA g⁻¹ and 1000 cycles, achieving a Coulombic efficiency of 99.6%. The high capacity of 381.0 mA h g⁻¹ can be attributed to the reversible Mg²⁺-ion intercalation mechanism observed in the MgV₃O₇∙H₂O phase using a 0.3 M Mg(TFSI)₂/ACN(H₂O) electrolyte. Additionally, within the voltage range of 2.25 V versus Mg/Mg²⁺, the V₂O₃@C exhibited a capacity of 245.1 mAh g⁻¹ when evaluated with magnesium metal in a 0.3 M Mg(TFSI)₂ + 0.25 M MgCl₂/DME electrolyte.
