Dear Anders,
Thank you for clarifications. I understand that by buckling the graphene ( depending on periods and amplitude), we may have a ripple structure.
I was working on the script under "Funwith graphene" and I can understand how we can buckle a graphene by considering the cooridinate x of an atom and also two periods (in length and width in z and y directions) as well as the amplitude. I need just to have the correct expression of the : Function for converting a nanosheet coordinate into a wobbled graphene nano-sheet. From the script, we may have the phases phi (y and z directions), but for a publication, it is important for the reader to have this function. I need you help help.
Best regards,
