Abstract
We reported an approach to grow carbon nanotube (CNT) arrays on graphene to obtain stable high emission current density along with scalable total ultrahigh emission current of more than 200 mA. Microwave plasma CVD was employed to grown multi-layered graphene directly on silicon wafer followed by synthesis of vertically well-aligned patterned CNT arrays, the excellent thermal conductivity and electric conductivity of graphene enabled CNTs to afford large emission current stably.
