摘要

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.
