Dear Jeetu Try Avogadro or Jmol to create graphene structure and find xyz coordinates of structure. The you can create fdf input file for further use in siesta. All the best.

If i want to calculate band structure of graphene, which parameter should I define? and how shall I be conform, my structure is that as desired like bended graphene stucture. Please help me to get out of this. Many thanks. Best regards, Jeetu donderiya Research Scholar ITM GOI, Gwalior
