报道了一种新的高稳定的有机分子 (SCN)可以和铜构成具有电双稳态特性的金属有机络合物。由这种材料制成的薄膜 ,在室温 6V电压作用下可以从高阻态转变成低阻态 ,其跃迁时间小于 2 0ns ,并具有极佳的热稳定性。因此可望用于制作电子器件 ,如一次写入存储器 (WORM)等。进一步的研究还发现 ,在适当的工艺条件下 ,SCN能够与Cu和Al一起构成Cu SCN Al结 ,这种结具有极性记忆效应 ,即只能被单向驱动 Reported a new high stability of organic molecules (SCN) and copper can be composed with the characteristics of bistable metal organic complexes. The thin film made of this material can change from high resistance state to low resistance state under the voltage of 6V at room temperature, the transition time is less than 20ns, and has excellent thermal stability. Therefore, it is expected to be used for fabricating electronic devices such as a write-once memory (WORM) and the like. Further studies have also found that SCN can form a Cu SCN Al junction with Cu and Al under appropriate process conditions. This junction has a polar memory effect that can only be driven in one direction
