beta-Graphdiyne (beta-GDY) is a two-dimensional carbon material with zero band gap and highly intrinsic carrier mobility and a promising material with potential applications in electronic devices. However, the synthesis of continuous single or ultrathin beta-GDY has not been realized yet. Here, we proposed an approach for ultrathin beta-GDY-like film synthesis using graphene as a template because of the strong pi-pi interaction between beta-GDY and graphene. The as synthesized film presents smooth and continuous morphology and has good crystallinity. Electrical measurement reveals that the film presented a conductivity of 1.30 X 10(-2) S.m(-1) by fabricating electronic devices on beta-GDY grown on a dielectric hexagonal boron nitride template.
