[Pw_forum] PAW potential for C

[chengyu yang]

Dear Everyone,
         I am looking for the paw potential for C atom with the PBE as
XC function, can anyone tell me how can I get such a potential?
         On the other hand, I googled the forum and somebody said the
choice of potential has no react to the result of binding energy, does
that mean whether I choose paw or normal potential, the result is the
same?
        Third problem, is the K point's setting has influence on the
calculation of binding energy? I found on this forum Dr. Nicola said
he would set the k point as gamma for all the calculations, but in all
the paper I read they use settings as 1*1*13 or something like that.
        Thank you. Best regards.
