Within density-functional theory, a linear combination of overlapping non-orthogonal orbitals from first principles may be utilized to arrive at at full-potential local orbital (FPLO) method [213], and this k-dependent LCAO approach comes close to full-potential APW-based methods (see Sections 2.15.3 and 2.15.4) in terms of numerical accuracy, although FPLO is much faster simply because of the locality of the basis set. Even faster, due to a strongly simplified potential, is a parameter-free (density-functional) tight-binding method called TB-LMTO-ASA, derived through localization of a delocalized basis set (see Section 2.15.4). [Pg.139]

Zhang and co-workers used this objective molecular-dynamics approach together with a density-functional tight-binding method to calculate the structural and electronic properties of M0S2 nanotubes of different diameters and chiralities. In order to characterize the objective... [Pg.131]

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... [Pg.632]

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]. [Pg.325]
