The world's first stable and controllable single-molecule electronic switching device
The use of single-molecule electronic devices is of great significance in breaking the bottleneck of the current miniaturization of semiconductor devices. The realization of a controllable single-molecule electronic switching function is the key to verifying whether a molecule can be used as a core component in an electronic device.
Since the 1970s, designing and constructing stable and controllable single-molecule devices, exploring its compatibility with microelectronics processes, and gaining a true sense of molecular electronic switching have made great scientific significance in contemporary nanoelectronics research.
On this basis, they collaborated with the Xu Hongqi Research Group of the Department of Electronics and Abraham Nitzan of the University of Pennsylvania to successfully overcome the core challenge of the strong coupling between diarylethene molecules and graphene electrodes through functionally oriented molecular engineering. Thus, a completely reversible light-induced and electric field-induced dual-mode single-molecule optoelectronic device was constructed in a breakthrough manner. This research work has led to the birth of the world’s first truly stable and controllable single-molecule electronic switching device in China.
The stable carbon skeleton of the graphene electrode and diarylene molecule, and the strong molecular/electrode-to-electrode covalent linking approach provide these single-molecule switching devices with unprecedented switching accuracy, stability and reproducibility, and highly integrated information in the future. The processor, molecular computer and precision molecular diagnostic technology have great application prospects.
The relevant research paper was published on June 17, 2016, Science (Science [352(6292): 1443-1445]). "Science" issued a commentary article during the same period: "This research has demonstrated the exquisite control of substances at the nanoscale."
