Few-layer-thick 2D materials offer desirable electronic, thermal and mechanical properties, but their large-scale layer-controlled synthesis is still challenging. Here, the authors report an edge-feeding synchronous epitaxial growth method to synthesize homogeneous A3-sized graphene films with controlled thickness between 2 and 7 layers.
