为了开发高密度存储器阵列,提出了一种基于Cu/SnO 2纳米棒阵列:ZnO纳米颗粒(NP)/掺氟氧化锡(FTO)结构的自整流阻变存储器,以避免寄生电流。该器件具有高的开/关比、高的耐久性和上级数据保持能力等优点。提出了一个基于SnO 2/FTO肖特基势垒、ZnO NP陷阱效应和Cu细丝的载流子输运模型来解释自整流阻变特性。该工作为有效避免寄生电流提供了一种新的方法,在构建高性能透明存储器阵列方面也显示了良好的前景。
To develop high-density memory arrays, a self-rectifying resistive random access memory based on a Cu/SnO2 nanorod array: ZnO nanoparticle (NP)/fluorine-doped tin oxide (FTO) structure is proposed to avoid the sneak current. The proposed device exhibits transparent property and significant merits including high ON/OFF ratio, conspicuous endurance and superior data retention. A carrier transport model based on a SnO2/FTO Schottky barrier, ZnO NP trap effect and Cu filament is proposed to explain the self-rectifying resistive switching performance. This work provides a new method to effectively avoid sneak current and also shows promising prospects in constructing high-performance transparent memory arrays.
