Atomistix ToolKit

Atomistix ToolKit (ATK) is a commercial software, developed by Atomistix 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^[1] and McDCal^[2], employing localized basis sets as developed in SIESTA^[3].

Features

Atomistix ToolKit^[4] combines density functional theory with non-equilibrium Green's functions for first principles electronic structure and transport calculations of

• electrode—nanostructure—electrode systems (two-probe systems)
• molecules
• periodic systems (bulk crystals and nanotubes)

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-based NanoLanguage scripting environment
