A new technique, electro‐hydrodynamic nanowire (e‐NW) lithography , is demonstrated for the rapid, inexpensive, and efficient fabrication of graphene nanorib bons (GNRs) on a large scale while simultaneously controlling the location and alignment of the GNRs. A series of interesting GNR architectures, including parallel lines, grids, ladders, and stars are produced. A sub‐10‐nm‐wide GNR is obtained to fabricate field‐effect transistors that show a room‐temperature on/off current ratio of ca. 70.
