分子电子学重大突破:室温可逆稳定单分子器件

Breakthrough of Molecular Electronics: Stable, Reversible Single Molecular Device at Room Temperature

分子电子学可追溯到费曼的幻想演讲。1959年底,费曼在加州理工举行的美国物理学会年会上发表了题为＂在底部有很大空间＂的讲演：＂我们为什么不能把计算机做小一点？譬如导线的直径小到10-100个原子,电路小到几千个埃,至少在我看来,物理学的规律不排除一个原子一个原子制造物品的可能性＂。20世纪70年代,Ratner等率先从理论上提出了分子整流器的设想。

Molecular connection between electrodes has been challenging the world since the concept of molecular electronics emergence in 1950s, and practical devices have remained elusive. Guo et al. made the breakthrough by covalently bonding a diarylethene molecule to graphene electrodes and achieved stable photoswitching at room temperature.
