제목 Patterned Growth of Graphene/Amorphous Carbon Heterostructure through One-Pot Synthesis
초록 Graphene is expected to play a role as an essential building block of 2D integrated circuit due to the simple modification of its electrical properties by doping and patterning. However, in order for 2D integrated circuit to be well worked, it is necessary to find another building block as insulator and combine these two building blocks into one circuit. Recently, although the lateral hetero-structures with graphene and hexagonal boron nitride can be grown using two-step CVD method, it is complicated and not applicable to the system with more than two components. Here, we report that one step growth of graphene/amorphous carbon (G/AC) hetero-structures from solid source as polystyrene (PS) via UV irradiation. The chemical pattern of neat/cross-linked PS via UV irradiation on copper foil converted to the pattern of G/AC in CVD. Because the resistance of amorphous carbon is 100 times higher than that of graphene, amorphous carbon is worked as insulator.
