Sequential experimental strategies of longitudinal unzipping of SWNTs: Selective width of single layer graphene nanoribbon

Single-layer graphene nanoribbon (sGNR) is a naturally good conductor and is a promising material for use as nanowiring in next generation computers. We have investigated a new fabrication method of sGNR by using a sonochemical technique to facilitate longitudinal unzipping of single-walled carbon nanotubes. The optimization of the fabrication process is discussed using a statistical analysis method of “Design of Experiment” to obtain the longest sGNR by unzipping of SWNT. The obtained results will contribute to downscaling of integrated circuits in the near future.
