now i am
working with LAMMPS to simulate the ion bombardement of ``Silicon(target) with gallium particles(more than one).And now i have some problems in setting force fields of zbl potential.
I set the Si atoms as type 1,and set Ga as type 2.I plan to use tersoff potential for Si-Si interactions,and zbl potential for Si-Ga and Ga-Ga interactions.Could anyone please tell me how to write my lammps commands?Thank you very much!
the lammps commands which i wrote are here.I also do not know the exact “inner” and “outer” value either
pair_style hybrid tersoff zbl inner outer
pair_coeff * * tersoff Si.tersoff Si NULL
