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[1]:“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[2]。80年代,随着自组装、有机分子束外延和扫描探针显微技术的发展,分子器件的研究取得了快速的
Molecular electronics can be traced back to Feynman’s fantasy lecture. At the end of 1959, Feynman delivered a speech titled “There is a lot of room at the bottom ” at the annual meeting of the American Institute of Physics held by the California Institute of Technology [1]: “Why can not we make the computer a little smaller? The diameter is as small as 10 to 100 atoms, the circuit is small to a few thousand angstroms, at least, in my opinion, the laws of physics do not rule out the possibility of an atom and an atom making an object. ” In the 1970s, Ratner and others took the lead in proposing the idea of a molecular rectifier in theory [2]. In the 1980s, with the development of self-assembly, organic molecular beam epitaxy and scanning probe microscopy, molecular devices have achieved rapid
