Application areas
Complex interface studies with ATK
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.
