Atomistix ToolKit (ATK) is a software package that offers unique capabilities for simulating electrical properties of nanodevices on the atomic scale:

• NEGF transport simulations 
• DFT, semi-empirical tight-binding, classical potentials
• Graphical user interface, with downloadable plug-ins that extends the functionality
• Python scripting interface
• Ability to handle large-scale systems

The software is used by over 100 research groups at leading universities, government labs, and companies around the world, in a wide range of application areas. Since 2006, over 400 scientific articles have been published using ATK. With its graphical user interface, ATK is also an ideal tool for teaching basic concepts of nanotechnology, solid state physics, etc.
