Currently the following version(s) of DFTB+ are available for download:

  • DFTB+ 1.2 (current stable release)
  • DFTB+ NEGF (feature prerelease with non-equilibrium Greens functions for electron transport calculations)
  • DFTB+ MPI (development snapshot of the MPI-parallelised version, for experienced users only!)


The DFTB+ code needs parameterisation data (Slater-Koster files) in order to perform calculations. These parameters are not distributed with the code.

You can download the Slater-Koster files from The Slater-Koster files are distributed under a different licence  from DFTB+, so you will have to sign a separate licence agreement to obtain these files. Please note that your account to download parameters at the site is separate to any account you may have at
