title: Upright standing graphene formation on substrates.
abstract: We propose integrating graphene nanoribbons (GNRs) onto a substrate in an upright position whereby they are chemically bound to the substrate at the basal edge. Extensive ab initio calculations show that both nickel (Ni)- and diamond-supported upright GNRs are feasible for synthesis and are mechanically robust. Moreover, the substrate-supported GNRs display electronic and magnetic properties nearly the same as those of free-standing GNRs. Due to the extremely small footprint of an upright GNR on a substrate, standing GNRs are ideal building blocks for synthesis of subnanometer electronic or spintronic devices. Theoretically, standing GNR-based microchips with field-effect transistor (FET) densities up to 10(13) per cm(2) are achievable.
