DIY molecular dynamics for Xenes on crystal surfaces; where can I get applicable open-source force field parameters that I can use in my scripts?

The linked question(s) below describes a DIY project to simulate how Xenes (honeycomb nets of atoms like graphehe) behave on single crystal surfaces. Behaviors include rotation, strain, and heigh ...

How to relate the degree of oxidation with the C/O ratio for the nanomaterials like graphene oxide?

I am currently working on the molecular modelling of Graphene oxide. It has different oxygen containing surface functionalities, so different degrees of oxidation. I am wondering if there is anyway to ...

Can I use the convergence test results of ecutwfc, ecutrho, and k points obtained from a 2x2 graphene supercell for a larger graphene supercell?

Recently, I conducted convergence tests (ecutwfc, ecutrho, and k points) for a 2x2 graphene supercell, yielding results of 120 Ry, 300 Ry, and 10x10x1 respectively. (Here, we considered convergence ...
