Atomistix ToolKit (ATK) is a commercial software, developed byAtomistix A/S, for atomic-scale modeling and simulation of nanosystems. Atomistix ToolKit is a further development of TranSIESTA-C, which in turn in based on the technology, models, and algorithms developed in the academic codes TranSIESTA [Brandbyge, Mozos, Ordejón, Taylor, and Stokbro, [http://dx.doi.org/10.1103/PhysRevB.65.165401 "Density-functional method for non-equilibrium electron transport"] , Physical Review B 65, 165401 (2002). ] and McDCal [Taylor, Guo, and Wang, [http://dx.doi.org/10.1103/PhysRevB.63.245407 "Ab initio modeling of quantum transport properties of molecular electronic devices"] , Physical Review B 63, 245407 (2001).] , employing localized basis sets as developed in SIESTA [Soler, Artacho, Gale, García, Junquera, Ordejón, and Porta, [http://dx.doi.org/10.1088/0953-8984/14/11/302 "The SIESTA method for ab initio order-N materials simulation"] , J.

Atomistix ToolKit [ [http://www.atomistix.com/index.php?id=atk atomistix | Atomistix ToolKit ] ] combines
density functional theory with non-equilibriumGreen's functions forfirst principles electronic structure and transport calculations of
*electrode—nanostructure—electrode systems (two-probe systems)
*molecules
*periodic systems (bulkcrystals andnanotubes )The key features are
*Calculation of transport properties of two-probe systems under an applied bias voltage
*Calculation of energy spectra, wave functions, electron densities, atomic forces, effective potentials etc
*Calculation of spin-polarized physical properties
*Geometry optimization
*A Python-basedNanoLanguage scripting environmentSee also
