Chinese scientists create new directions for research on carbon family single crystal materials to open up carbon materials

Xinhua News Agency, Beijing, June 16 (Reporter Zhang Quan) Fullene, carbon nanotubes, graphene ... Every discovery in the field of new carbon materials has had an important impact on human technology progress. Chinese scientists have successfully created a new carbon family single crystal material -single -layer polymerization carbon 60, which is a new cluster two -dimensional super structure, providing a new idea for the research of carbon materials.

The research was completed by Zheng Jian's team of Zheng Jian, a researcher at the Institute of Chemistry of the Chinese Academy of Sciences, and published on the 15th on the 15th on the 15th on the 15th in the international academic journal "Nature" online.

Carbon materials are widely used in the fields of transistor, energy storage, superconducting and other fields due to their own excellent strength, heat, light, electricity and other attributes. Some material scholars believe that human society will enter the "carbon -based electronics era" from today's "Silicon -based Electronics Age". Therefore, preparation of new carbon materials has always been a cutting -edge scientific issue in the field of materials.

"The performance of carbon materials is closely related to its topological structure. The biggest breakthrough of this study is to build carbon materials with carbon clusters instead of carbon atoms." Zheng Jian introduced that the minimum unit of two -dimensional materials was a single atom, and the carbon cluster was caused by the carbon cluster. Multiple carbon atom composition, such as carbon 60 is a spherical structure composed of 60 carbon atoms. The team believes that building a two -dimensional material with carbon clusters is expected to obtain more novel performance.

However, before that, carbon clusters built a higher -level two -dimensional topology structure with carbon clusters. "Because the reaction income of carbon carbon is not 100%and the response is irreversible, the use of traditional chemical reactions from bottom to top to prepare two -dimensional cluster carbon material single crystals through molecular bricks." Jian said.

In this regard, through 5 years of concentrated research, the team finally used the doped aggregation-stripping two steps under normal pressure, and successfully prepared a single-layer two-dimensional aggregate carbon 60 single crystal. The price key forms a rule of the topology.

Studies have shown that single -layer polymerization carbon 60 has good thermodynamic stability, and still exists stable at 300 degrees Celsius high temperature. This material has important application prospects in optical/electronic semiconductor devices, non -linear optical and functional electronic devices. It also has application potential in the fields of superconducting, quantum computing, information and energy storage, and catalytic.
