Welcome to DFTB!
This site contains some information about the Density Functional based Tight Binding (DFTB) method. If you want to know more about this fast and efficient quantum mechanical modelling method, you should read this short description about DFTB and eventually some references about the method and its applications.
The DFTB method has several implementations. For a (non complete) list of the available codes, see the implementations subpage.
If you are looking for parameters (Slater-Koster files), you can download various parameter sets for DFTB+ and DFTB/Gaussian (soon).
New set for Zn and ZnO with organic molecules 2009-04-02
The new parameter set znorg had been published. The new set was developed in Bremen (BCCMS) and extends the current mio set with Zn. The set was created to enable a good description of the following systems with DFTB: bulk Zn, bulk ZnO, ZnO surfaces and nanowires, interaction between the various ZnO structures and organic molecules, and Zn in biological systems.

New set for Eu in GaN 2008-11-12
A new parameter set (rare) for treating Eu in GaN had been uploaded to the web page. Other rare earth elements should follow. The set had been created by Simone Sanna (University of Paderborn, Paderborn, Germany).
