This directory contains potential files for different elements and alloys, as used by LAMMPS for various pair styles. See the description of the "pair_style" and "pair_coeff" commands for details of the file formats and the various styles in LAMMPS that read these files.

The prefix of each file indicates the element(s) it is parameterized for. An additional lower-case identification tag may be appended.

Si = Silicon SiC = Silicon and Carbon Au_u3 = Gold universal 3

For many of the files, comments in the header section give origin and citation information.

The suffix of each file indicates the pair style it is used with:
