The pitch solution is spin-coated on a silicon wafer without using a catalyst support. After stabilization and carbonization, the CNSs as thin as 2 nm show an electrical conductivity of approximately 30,000 S/m. Although the CNSs do not have a well-developed graphitic structure, as observed using Raman spectroscopy and transmission electron microscopy, they are conductive enough for use as electrodes in an organic thin film transistor.
