Layer-Stacking Growth and Electrical Transport of Hierarchical Graphene Architectures

Hierarchical graphene architectures (HGAs) that grow by stacking of layers are produced on a liquid copper surface using chemical vapor deposition. The stacking mode — for example hexagonal–hexagonal–hexagonal or hexagonal–snowflake–dendritic — can be simply controlled. Measurements of the electrical properties of HGAs indicate that hierarchical stacking of graphene may be a simple and effective way of tailoring their properties without degrading them.
