Atomistix ToolKit (ATK) from QuantumWise is a software package that offers unique capabilities for simulating electrical transport properties of nanodevices on the atomic scale. Based on an open architecture which integrates a powerful scripting language with a graphical user interface, ATK is a comprehensive platform for studies in nanoelectronics, using methods that range from both accurate quantum-mechanical first-principles and fast semi-empirical methods to classical potentials for very fast geometry optimizations and molecular dynamics calculations.
A special focus is placed on treating large-scale systems, with several thousand atoms. Moreover, ATK includes a very advanced electrostatic model to allow realistic simulations of nanoscale transistor structures.
