Logic operation of the micro-scale logic gate single molecular junction under an electrical control condition is realized, and the logic gate single molecular junction has extremely high logic operating rate and response capability; and meanwhile, real single molecular operation capability is provided by the logic gate single molecular junction, so that an important foundation is laid for the replacement of a silicon semiconductor technology.

Description

technical field [0001] The invention relates to a logic device, in particular to a single molecular junction logic gate. Background technique [0002] Logic gates are the basic components of integrated circuits. Computers that are widely used today are mainly silicon semiconductor integrated circuits. For traditional silicon semiconductor integrated circuits, their computing power is highly related to the size of the semiconductor unit. When the semiconductor is densely packed to a certain extent At this time, the circuit will produce overheating and cross-interference that are difficult to overcome. Further narrowing the electronic conduction line width, reducing the size of the computer, reducing the cost and power consumption, and increasing the computing speed are close to the limit in theory and technology. In recent years, scientists have been trying various nanoparticle methods and concepts, trying to replace silicon semiconductors. As the concept of logic gates, on ...
