Atomistix ToolKit (ATK) is a software package that offers unique capabilities for simulating nanostructures on the atomic scale

• NEGF simulations  to study transport properties like I-V characteristics of nanoelectronic devices
• Powerful combination of DFT, semi-empirical tight-binding, classical potentials in the same package
• Advanced graphical user interface for building complicated structures like interfaces and transport systems
• Plugin-based platform which can interface with external codes
• Python scripting interface

The software is used by over 120 research groups at leading universities, government labs, and companies around the world, in a wide range of application areas. Since 2006, almost 500 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.
