【摘要】 报道一种可逆转换的分子基电双稳薄膜器件,Al/BN4/Al/BN4/Al.其中功能层为有机/金属/有机的夹层结构,而中间金属层要非常薄.该器件在较低电压作用时呈现高阻状态,阻值在106~109Ω;而当电压超过某一阈值时,器件导电态发生改变,由高阻态跃迁为低阻态,阻值约为102~105Ω.两种状态的电阻值比为103~105.另外,还比较了不同功能层厚度器件的性能.更多还原

【Abstract】 It is reported a kind of molecular-based electrical bistable device Al/BN4/Al/BN4/Al,where a thin metal layer is embedded within the organic material as the active medium.The device exhibits a high-resistance state(10~6—10~9 Ω) under a lower voltage,whereas it retains a low-resistance state(10~2—10~5 Ω) upon a higher voltage.The resistance ratio of the two states is about 10~3—10~5.Furthermore,the situations of different depth of the active medium have also been compared.更多还原
