In order to build the cell we can use a CNT generator, several options available:
- go to CNT generator http://turin.nss.udel.edu/research/tubegenonline.html
- For simplicity set the crustal cell as cubic
- Choose a format with PBC (e.g. PDB with PBC). Note that the units are in Angstrom.
- Build the input file.
Note the tube axis is along z.
Suggestions: (Use ibrav=8, set an arbitrary amount of vacuum, and set cilldm(3)=c/a)
- Visualize the structure using xcrysden
