|---|---|---|
| Molecular Dynamics | md_$(SYS) | empty potential, for visualization and atom manipulation |
| Finnis-Sinclair | fs_$(SYS) | BCC metals (Mo, Ta, W, ...) |
| Embedded Atom Method | eam_$(SYS) | FCC metals (Cu, Au, ...) |
| Aluminum Glue | alglue_$(SYS) | Al (FCC metal) |
| Modified Embedded Atom Method | meam_$(SYS) | FCC metals, BCC metals, semiconductors |
| Lennard-Jones | lj_$(SYS) | Noble gas (Ar, ...) |
| Stillinger-Webber | sw_$(SYS) | Semiconductors (Si, Ge, C) |
| Tersoff | tersoff_$(SYS) | Semiconductors (Si, Ge, C) |
| Brenner | brenner_$(SYS) | C, hydrocarbons |
"Potential" Problems
These are some potential files we used in our simulations of molecular structures. Please note that since we use a variety of codes, the potential files will be in a variety of foremats. The most common codes used by our group are LAMMPS ( and ParaDyne) and MD++. These codes use different file formats for EAM potentials, so all files should specify which file format. We will also try to provide a reference describing the potential.
