论文摘要
我们报告了在环境条件下的磁性，导电和稳定的原始晶体3D碳的发现。这种碳材料数十年来一直难以捉摸，它通过使用特定有机分子前体3,3-二甲基-1-丁烯（C6H12）的化学蒸气沉积（CVD）技术合成。对势能表面的详尽计算搜索揭示了其独特的SP2-SP3混合键合拓扑。涉及大量实验技术和多尺度第一原理计算的协同研究揭示了由于晶格中SP2碳原子的特殊排列，其新型特性的起源。由于其不寻常的结构和特性而命名的U-碳的发现可以打开碳科学的新章节。
We report the discovery of a pristine crystalline 3D carbon that is magnetic, electrically conductive and stable under ambient conditions. This carbon material, which has remained elusive for decades, is synthesized by using the chemical vapor deposition (CVD) technique with a particular organic molecular precursor 3,3-dimethyl-1-butene (C6H12). An exhaustive computational search of the potential energy surface reveals its unique sp2-sp3 hybrid bonding topology. Synergistic studies involving a large number of experimental techniques and multi-scale first-principles calculations reveal the origin of its novel properties due to the special arrangement of sp2 carbon atoms in lattice. The discovery of this U-carbon, named such because of its unusual structure and properties, can open a new chapter in carbon science.
