Journal ArticleDOI

The SIESTA method for ab initio order-N materials simulation

TL;DR: In this paper, a selfconsistent density functional method using standard norm-conserving pseudopotentials and a flexible, numerical linear combination of atomic orbitals basis set, which includes multiple-zeta and polarization orbitals, was developed and implemented.
Journal ArticleDOI

Density-functional method for nonequilibrium electron transport

TL;DR: In this paper, an ab initio method for calculating the electronic structure, electronic transport, and forces acting on the atoms, for atomic scale systems connected to semi-infinite electrodes and with an applied voltage bias.
Journal ArticleDOI

Self-consistent order- N density-functional calculations for very large systems

TL;DR: A method to perform fully self-consistent density-functional calculations that scales linearly with the system size and which is well suited for very large systems is presented, using strictly localized pseudoatomic orbitals as basis functions.
Journal ArticleDOI

Density-functional method for very large systems with LCAO basis sets

TL;DR: In this article, a linear scaling, fully self-consistent density-functional method for performing first-principles calculations on systems with a large number of atoms, using standard norm-conserving pseudopotentials and flexible linear combinations of atomic orbitals (LCAO) basis sets, was implemented.
Journal ArticleDOI

Tight-binding description of graphene

TL;DR: In this article, the authors investigated the tight-binding approximation for the dispersion of the electronic bands in graphene and carbon nanotubes, and derived an analytic expression for the tightbinding dispersion including up to third-nearest neighbors.
