Carbon nanotube graphoepitaxy: Highly oriented growth by faceted nanosteps

Ariel Ismach, David Kantorovich, Ernesto Joselevich

Research output: Contribution to journalArticlepeer-review


Single-wall carbon nanotubes grow along self-assembled nanosteps of annealed miscut C-plane sapphire. Depending on the miscut orientation and annealing conditions, graphoepitaxy leads to the formation of either unprecedentedly straight and parallel nanotubes, with angular deviations as small as ±0.5°, or to wavy nanotubes loosely conformal to sawtooth-shaped faceted nanosteps.
