Parameter set "chalc-0-1"

This special parametrization was used to investigate defects in chlacogenide glasses (amorphous As2S3) and extends the earlier parametrization of the As-S-H hyb-0-1 set by using d-orbitals on As. This was necessary in order to get a qualitative correct picture for overcoordinated As defects in these systems.

Warning: This set was not optimized for the calculation of reaction and binding energies. It delivers correct electronics and geometries and can be used for TD-DFTB calculations. A general validation wrt to molecules/surfaces/bulk was not performed.
