摘要
介绍一种基于C60/Polymethyl Methacrylate(PMMA)复合体系的电双稳器件,在室温下的I-V测试曲线表明器件具有电双稳特性,并且可实现稳定的"读-擦-读-写"操作。C-V测试曲线表明器件存在一个平带电压的偏移是由于存在C60分子的缘故,这说明C60分子在器件的工作过程中起到对载流子的陷获、存储以及释放的作用。在器件C-V特性曲线的基础上,阐述了载流子的输运机制。
An organic/inorganic hybrid bistable device based on C60 molecules embedded in PolymethylMethacrylate （PMMA） layer was reported. Current-voltage （I-V） measurements at room temperature showed a nonvolatile electrical bistability behavior, and repeatable operation of ＂read-erase-read-write＂ was also achieved. Capacitance-voltage（C-V） measurements were carried out to investigate the carrier capture and release mechanism of the device, the result witnessed a metal-insulator-semiconductor behavior with a flatband voltage shift due to the existence of the C60 molecules. The carrier transport mechanism in this device was described on the basis of the CV results.
