Timothy H.Vo and his colleagues present a new type of nitrogen-doped graphene nanoribbons (GNRs), which shows a great potential to create novel nanoscale both 2D and 3D metamaterials. Atomically precise bottom-up synthesis has been used on a surface and in solution in order to fabrication these planar and 3D crystalline GNRs. Technologies such as Scanning tunneling microscopy (STM), Scanning tunneling spectroscopy (STS), transmission electron microscopy (TEM), X-ray scattering as well as photoluminescence (PL) spectroscopy and UV-vis absorption spectroscopy are used to measure the performance of the structures which are outstanding, compared to other similar nanostructures. As nanoscale building blocks, the reported 8N-GNRs structure provides a rapid developing toolset to realize families of novel carbon-based materials with engineered properties.
