| 题目: | One-Step Fabrication of CdS:Mo�CdMoO4 Core�Shell Nanoribbons for Nonvolatile Memory Devices with High Resistance Switching | | 作者: | Ni Zheng, Zhibin Shao,* Feifei Xia, Tianhao Jiang, Xiaofeng Wu, Xiujuan Zhang,* Jiansheng Jie* and Xiaohong Zhang | | 单位: | Institute of Functional Nano & Soft Materials (FUNSOM), Collaborative Innovation Center of Suzhou Nano Science and Technology (Nano-CIC), Jiangsu Key Laboratory for Carbon-Based Functional Materials & Devices, Soochow University, Suzhou, Jiangsu 215123, P. R. China. | | 摘要: | Nano-field-effect transistor (nano-FET)-based nonvolatile memory (NVM) devices fabricated from one-dimensional (1D) nanostructures have attracted much attention due to their superior memory performance. However, the construction of NVM devices is relatively complex due to the multi-step process needed to fabricate the trapping/tunneling layers. Here, we report a one-step fabrication of CdS:Mo�CdMoO4 core�shell nanoribbons (NRs) for high-performance nano-FET-based NVM devices. The CdMoO4 shell could serve as both the charge storage media and tunneling layer, thus greatly facilitating the device construction. The resultant NVM devices exhibited a large memory window of 60 V as well as a long retention time of 3600 s. Significantly, the devices showed an excellent resistance switching behavior with a current ON/OFF ratio as high as 106, which is larger than those of most 1D nanostructure-based nano-FET memories. A mechanism associated with defect states caused by oxygen vacancies in the CdMoO4 shell was proposed to interpret the memory characteristics. Given the excellent memory performance, along with the simple one-step fabrication process, CdS:Mo�CdMoO4 NR-based NVM devices will have important applications in new-generation high-performance NVM devices. | | 影响因子: | 5.256 | | 分区情况: | 一区 | | 链接: | http://pubs.rsc.org/en/content/articlelanding/2017/tc/c7tc01230f#!divAbstract |
