大规模单晶石墨烯的制备由于其高质量和优异的物理性能而备受关注，这在电子学和光电子学应用中具有重要意义。在这里，通过商业印刷辅助化学气相沉积工艺，成功地制造了排列良好的亚毫米尺寸的单晶石墨烯阵列。该方法将碳前驱体点以设计的图案印刷在铜箔上，作为成核中心，在设计的位置诱导石墨烯畴的生长。本研究为大规模合成单晶石墨烯阵列提供了一条简便的途径，对构建实际应用的石墨烯器件具有重要意义。
Much attention has been focused on the fabrication of large-scale single-crystalline graphene due to its high quality and impressive physical properties, which are essential and significant in electronics and optoelectronics applications. Here, well-aligned submillimeter-sized single-crystalline graphene arrays were successfully fabricated by a commercial printing-assisted chemical vapor deposition process. In this method, carbon precursor dots can be printed on Cu foil with a designed pattern, which can serve as the nucleation centers to induce the growth of graphene domains at the designed locations. This work provides a facile route to synthesize single-crystalline graphene arrays on a large scale, which is of great significance in building graphene devices for practical applications.
