中文摘要： 有机/无机纳米复合材料因兼具了纳米粒子和有机材料二者的优良性能，成为有机电子学与信息存储交叉领域关注的焦点之一。在该领域的研究中，一些材料表现出一定的电学双稳特性，在下一代非易失性存储器中表现出巨大潜力，但对于有机/复合材料中电双稳态的形成机理至今仍未有统一解释。随着无机纳米/有机薄膜在微电子和光电子元件中的广泛应用，纳米/有机界面电传输对器件性能的影响及规律，是一个值得深入探索的研究课题。本项目利用纳米结构和能带工程构建I型纳米材料,利用湿化学法,原位同步材料生长形成有机/无机纳米结构的复合体系, 从而达到均匀的薄膜，实现对电荷有效俘获和存储控制,从而提高双稳态器件性能。本项目的研究对研究无机纳米材料与有机材料的相互作用，界面电荷极化、转移的探索方面有重要的理论意义。此外，其电双稳态特性对于制备开关比高、稳定性好及环境友好的器件具有很好的应用价值和现实意义。

英文摘要： Organic/nano-hybrid materials show the advantages of low-cost, easy processing, small size, fast response, low power and flexible. In the past few decades, it have attracted much attention due to their applications in optical and electrical devices, such as light-emitting diodes, solar cells,field-effect transistors and information storage. The organic/inorgnic nano composite matericals becomes a focus in the research of organic electronics and information storage because of its excellent properties from nanoparticles and organic materials. In this field, the electrical bistability of the hybrid materials shows a great potential in next-generation non volatility memories. However, the mechanism of organic/inorganic nanomaterials electrical bistability hasn't been well understood, and some fundamental questions such as new concepts and theories, new structures, methods, technologies and materials involved during the fabrication and processing need to be further investigated. In this project, new nanostructure oxide will be embed into polymers，and many fundamental mechanisms such as interaction, charge transfer and polarization between nanoparticles and polymers will be studied.
