[Pw_forum] Regarding adsorption of metal atoms in graphene

[Mansoureh Pashangpour]

Dear S. Appalakondaiah,
First you should construct your 2D system and find the best values for
kpoint,Ecut,Ecutrho,.. . For graphene you can consider a hexagonal cell
with 2 carbon atoms. After full relaxation, cell parameter, a, will be
find. you must have a large c cell parameter to avoid parallel 2D layers.
to study absorption you must have a super cell. Finally you add metal
atom  to the system. you must change ntype, number of atoms, add its
pseudopotential and its position to your input file. after that relax the
system again.
regards,
