The rapid development of information technology has led to an urgent need for devices with fast information storage and processing, a high density, and low energy consumption. Memristors are considered to be next-generation memory devices with all of the aforementioned advantages. Recently, organometallic halide perovskites were reported to be promising active materials for memristors, although they have poor stability and mediocre performance. Herein, we report for the first time the fabrication of stable and high-performance memristors based on inorganic halide perovskite （CsPbBr3, CPB）. The devices have electric field-induced bipolar resistive switching （ReS） and memory behaviors with a large on/off ratio （〉105）, low working voltage （〈1 V） and energy consumption, long data retention （〉104 s）, and high environmental stability, which are achieved via ZnO capping within the devices. Such a design can be adapted to various devices. Additionally, the heterojunction between the CPB and ZnO endows the devices with a light-induced ReS effect of more than 103 with a rapid response speed （〈1 ms）, which enables us to tune the resistance state by changing the light and electric field simultaneously. Such multifunctional devices achieved by the combination of information storage and processing abilities have potential applications for future computing that transcends traditional architectures.

针对目前工程中存在的框架结构越层柱如何考虑其二阶效应的设计方法问题,以GB 50010—2002《混凝土结构设计规范》提供的基于经典结构稳定理论的二阶效应计算方法(η-l_0法)为依据,提出计算越层柱等效长度系数μ的简化计算方法——基于构件实际约束状态下的分离杆件法。经大量基于实际工程经验算例的对比与分析,总结出适用于框架结构首层越层柱取1.05,中间层越层柱取1.15,顶层越层柱取1.8的等效长度系数μ的取值建议,将μ值代入传统η-l_0法中即可方便准确地计算越层柱考虑二阶效应的内力值。经算例验证表明,文中提供的越层柱考虑二阶效应的设计方法较好地反映了框架结构中越层柱在考虑二阶效应影响下的受力规律与变形特征,可用于工程设计并为规范相关条文修订以及后续研究提供参考。

Deep-level traps at the buried interface of perovskite and energy mismatch problems between the perovskite layer and heterogeneous interfaces restrict the development of ideal homogenized films and efficient perovskite solar cells(PSCs)using the one-step spin-coating ***,we strategically employed sparingly soluble germanium iodide as a homogenized bulk in-situ reconstruction inducing material preferentially aggregated at the perovskite buried interface with gradient doping,markedly reducing deep-level traps and withstanding local lattice strain,while minimizing non-radiative recombination losses and enhancing the charge carrier lifetime over 9μ***,this gradient doping assisted in modifying the band diagram at the buried interface into a desirable flattened alignment,substantially mitigating the energy loss of charge carriers within perovskite films and improving the carrier extraction *** a result,the optimized device achieved a champion power conversion efficiency of 25.24% with a fill factor of up to 84.65%,and the unencapsulated device also demonstrated excellent light stability and humidity *** work provides a straightforward and reliable homogenization strategy of perovskite components for obtaining efficient and stable PSCs.
