About Stillinger Weber Potential File of MoS2


I have uploaded an image of sw potential parameters of MoS2.
There are only 2 types of atoms in MoS2. So like GaN sw potential file there should be 8 rows for different atom combinations. But in the table what is meant by Mo3, S3 etc. In this case, how can i make the potential file for MoS2 mono-layer sheet?

Not necessarily. There are two elements, but you may have a structure where you have elements in different environments. In a classical force field those may be represented by different atom types. E.g. in molecular force fields, you have many different types of carbon atoms, or hydrogen atoms.

That is a question that should be answered in the publication that you took the table from.
