The preceding methods discussed in this section are semiempirical MO methods. The SCC-DFTB method (self-consistent-charge density-functional tight-binding method) is a semiempirical DFT method [M. Elstner et al., Phys. Rev. B, 58, 7260 (1998) M. Elstner, Theor. Chem. Acc., 116, 316 (2006)], somewhat similar to the semiempirical MO methods. The exchange-correlation energy functional used in SCC-DFTB is usually the PBE functional (Section 16.5). The SCC-DFTB method treats only the valence electrons... 

Early implementations of dispersion corrections in computational chemistry methods were realized in HF calculations. A similar approach was applied in SCC-DFTB (self-consistent charge density functional tight-binding method) [28, 32] and dispersion correction to energies computed with conventional DFT functional was described [33].
