I'm trying to calculate the thermal properties of Silicene with hydrogen and halogen atoms. My problem is that, there's seems no available potential for Tersoff and Stillinger Weber Potential. and I'm looking everywhere to find one. Where I can get one tho? I'm still new to this hope you all understand.
The comments are correct in directing you towards literature and the LAMMPS potential directory. For future reference as well, NIST maintains a page which contains many empirical potentials for most elements: https://www.ctcms.nist.gov/potentials/
