First-principles simulation software for nanoscience
Atomistix ToolKit (ATK) from QuantumWise is a quantum-mechanical 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 both accurate first-principles and fast semi-empirical methods.
A special focus is placed on treating large-scale systems with upwards of 1,000 atoms. Moreover, ATK includes a very advanced electrostatic model to allow realistic simulations of nanoscale transistor structures.
ATK also offers basic electronic structure calculations, including geometry optimization, of molecules and periodic structures like bulk crystals, nanotubes, slabs, etc.
The software is used by over 100 research groups at leading universities, government labs, and electronics companies around the world, in a wide range of application areas. Since 2006, over 250 scientific articles were published using ATK, and many new unique features are planned for release already during 2010.

The materials involved in novel semiconductor circuits are becoming more and more complex, which is not least evident in the latest generation of gate stacks involving high-k dielectrics. In addition to the pure material properties, the focus of research is now on modeling advanced junctions and interfaces between different materials. For this, a detailed description on the quantum-mechanical level is required, in order to calculate e.g. the leakage current or Schottky barrier. Moreover, since these interfaces are very thin, even on a nanoscale level, defects play a crucial role. Therefore, an atomistic description is needed to be able to predict how impurities, vacancies, etc influence the properties of the junction. Several academic researchers, including Prof. Nishi's group at Stanford, are using Atomistix ToolKit (ATK) from QuantumWise to model such structures. |
