[lammps-users] What potential should I use for Co-Co, Co-Au, Au-Au

Dear All:

It seemed EAM can be applied to both Co-Co and Au-Au, but how about Co-Au. I found some information on an article saying that The second-moment approximation of tight-binding potential (SMA-TB) is used for Co-Au. So my questions are:

  1. Is it included in Lammps? If not, is there any similar potential that I can use?

  2. For Co-Co, where I can find the pair coeff. I’ve referred to some websites suggested in the Manual. But I could not find one.

Thanks

LAMMPS has no tight-binding potentials.
