An undoped organic small-molecule 2-(4-tert-butylphenyl)-5-(4-biphenylyl)-1,3,4-oxadiazole (PBD) and a kind of nanocomposite blending poly(methyl methacrylate) (PMMA) into PBD are employed to implement bistable resistive switching. For the bistable resistive switching indium tin oxide (ITO)/PBD/Al, its ON/OFF current ratio can touch 6. What is more, the ON/OFF current ratio, approaching to 10(4), is available due to the storage layer PBD:PMMA with the chemical composition 1:1 in the bistable resistive switching ITO/PBD:PMMA/Al. The capacity, data retention of more than 1 year and endurance performance (>10(4) cycles) of ITO/PBD:PMMA(1:1)/Al, exhibits better stability and reliability of the samples, which underpins the technique and application of organic nonvolatile memory.
采用未掺杂的有机小分子2-(4-叔丁基苯基)-5-(4-联苯基)-1,3,4-恶二唑(PBD)以及一种将聚甲基丙烯酸甲酯(PMMA)混入PBD的纳米复合材料来实现双稳态电阻开关。对于双稳态电阻开关氧化铟锡(ITO)/PBD/Al，其开/关电流比可达6。此外，在双稳态电阻开关ITO/PBD:PMMA/Al中，由于化学组成为1:1的存储层PBD:PMMA，开/关电流比可达10⁴左右。ITO/PBD:PMMA(1:1)/Al的电容、超过1年的数据保持能力以及耐久性(>10⁴次循环)，表明样品具有更好的稳定性和可靠性，这为有机非易失性存储器的技术和应用提供了支持。
