[DFTB-Plus-User] C-C Slater-Koster File Suitable for Electronic-Bandstructure Calclations

PBC set is not meant to calculate conduction band features. (Reproduces
only VB correctly.) Unfortunately, all available sets on DFTB.ORG for
carbon only include s and p orbitals, so none of them would give you a
correct conduction band.

Best regards,

Bálint
