A novel approach for the rational synthesis of low‐defect density, patterned graphene from the bottom up, called barrier‐guided chemical vapor deposition, is introduced. A patterned barrier layer impedes the growth of graphene in selected areas of the copper substrate, guiding the growth of graphene into desired micro‐ and nano‐ structures with control over placement, orientation, and spatial and lateral extent.
