Atomic force microscopy study of nitrogen molecule self-assembly at the HOPG-water interface

- Investigating evolution of nitrogen molecule self-assembly at the graphite-water interface.
- Imaging with highly sensitive frequency-modulation atomic force microscopy.
- Nucleation and growth of an ordered row-like structure is observed.
- Nitrogen clusters appear when the coverage of the ordered structure exceeds 50%.
- A model of how nitrogen molecules adsorb and self-assemble is proposed.
