摘    要:报道了一种新型有机材料AOSCN(3,9-双(10-(二氰基亚甲基)-9-亚甲蒽基)-2,4,8,10-四硫杂螺[5,5]十一烷),能与Cu形成具有电双稳特性的络合物,在6V电压下,薄膜发生从高阻态到低阻态的转变,跃迁时间小于30ns,驰豫时间小于1μs。若薄膜已发生高阻态到低阻态转变,高温热处理能使其恢复初始状态,这有望制成可擦写存储器。此外,在一定的工艺条件下,AOSCN与Cu和Al形成的金属-有机-金属(MOM)结,具有极性记忆效应。

关 键 词:有机络合物 电双稳态 极性记忆效应 热可擦

Abstract:A metal-orgainc complex thin film, constructed by Cu and a new organic material AOSCN (3,9-di (anthracene-10-(dicyanomethylene)-9-) -2,4,8,10-tetrathiaspiro[5,5]undecane) was reported. The complex shows good electrical bistability. The device with a sandwich structure can be transferred from high to low-impedance under 6 V with delay and switching times of less than 1000 and 30 ns, respectively. The anneal can erase the low state. Further investigation found that the junction of Cu/AOSCN/Al exhibits polarized memory effect in certain condition.
Keywords:Organic complex  Electrical bistable states  Polarized memory effect  Thermally erasable
