According to the news of September 6, according to CCTV News, after years of research and research, Chinese scientists have achieved the first atomic-level precise control of graphene folding in the world. This is the world ’s smallest size of graphene folding. Quantum devices are of great significance. This result was published today in the international academic journal Science.
It is understood that exploring new low-dimensional carbon nanomaterials and their novel physical properties is one of the world's leading scientific issues. Related research has won the Nobel Prize twice. At present, there are still huge challenges in accurately constructing and controlling low-dimensional carbon nanostructures based on graphene at the single atom level.
After research, the research team of the Institute of Physics of the Chinese Academy of Sciences realized for the first time the atomically precise and customized controllable folding of graphene nanostructures to construct a new type of quasi-three-dimensional graphene nanostructures.
It is understood that the research result is the world's smallest size graphene controllable folding. Based on this atomically accurate "origami", other novel two-dimensional atomic crystal materials and complex laminated structures can also be folded to prepare functional nanostructures and their quantum devices.
Gao Hongjun, an academician of the Chinese Academy of Sciences, said that after folding, these new two-dimensional atomic crystal materials may change from no superconductivity to superconductivity, and no magnetism to magnetism.
He said that using such changes in characteristics to construct functional quantum devices will have important implications for future applications, such as quantum computing.
