Dear Zhigong,
Our ‘best’ set of parameters for DFTB spans C-H-N-O. I am working on developing others that I’ll release through the github site once they’re ready. We will shortly have a paper out in J. Chem. Theory Comput. that details how users can develop their own parameter sets. Stay tuned.

    Hi - Marc and Christian are the right folks to answer this,
    as it's really a LATTE Q.  I'm also CCing this to
    the LAMMPS mail list, as I think the Q/A will be of
    general interest to other LAMMPS users who want
    to try out tight-binding and LATTE.
    Marc/Christian - if you CC the mail list address
    in your replies, the info should appear there as well.
