WebDFTB+¶ Introduction¶. DFTB+ is a density-functional based tight-binding code using atom-centered orbitals. This interface makes it possible to use DFTB+ as a calculator in ASE. You need Slater-Koster files for the combination of atom types of your system. These can be obtained at dftb.org.. Environment variables¶ http://www.dftb.org/

WebApr 14, 2024 · DFTB is 2–3 orders of magnitude faster than DFT, allowing calculations containing up to ca. 5000 atoms.
