Atomistix ToolKit

Atomistix ToolKit (ATK) is a commercial software for atomic-scale modeling and simulation of nanosystems. The software was originally developed by Atomistix A/S, and was later acquired by QuantumWise A/S following the Atomistix bankruptcy.[1]

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[2] and McDCal,[3] employing localized basis sets as developed in SIESTA.[4]


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

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
