SiGe potential

Dear Users,
Is any potential available in LAMMPS by which simulation can be done for a system containing both Silicon as well as Germanium atoms?
Please suggest me if anybody has any idea.

Thanks and Regards

That can likely be done with a Tersoff potential. E.g. there
is a SiCGe tersoff potential included with LAMMPS, so someone (you)
could create a SiGe potential file.
