Oxidation tunes various properties of graphene by changing carbon from sp2 to sp3 type. Such a change is detectable with Raman spectroscopy. Tip-enhanced Raman scattering 每 a method that combines Raman spectroscopy with scanning probe microscopy can detect localized oxidation and induce oxidation sites on graphene with subnanometer spatial precision.

Polymerization via plasmon-excited hot electrons enables controllable polymer growth with nanoscale precision. The polarization-dependent near-field profile around gold nanoparticles guides the polymer growth into anisotropic features with local selectivity, which significantly advances the control of polymer growth at nanoscale.

Since its discovery, the direct imaging and determination of the crystal structure of few-layer graphdiyne has proven difficult. In this work, we successfully employed low-voltage transmission electron microscopy with low current density to realize the direct imaging of graphdiyne and confirmed that the structure of an as-synthesized graphdiyne nanosheet is crystalline, with six-layer thickness and ABC stacking.
