RSPACE

  • 公開度：1 ★☆☆
  • ドキュメント充実度：2 ★★☆

RSPACE is a first-principles code package based on a real-space finite-difference pseudo-potential method. It computes electronic states with high-speed and high precision in aperiodic systems of surfaces, solid interfaces, clusters, nanostructures, and so forth. It provides large-scale computing for semiconductor devices of nanostructure surface and interface reactions, calculation of transport properties in semi-infinite boundary conditions, and a massively parallel computing using the space partitioning method.

その他 RSPACE performs first-principles calculations based on the density functional theory using the real-space finite-difference method suited for massively parallel computers. The software uses PAW for pseudopotentials, a method that is the best in terms of both computational cost and precision, enabling high-precision computation of models containing transition metals as well. The electron state can be calculated, in addition to the electric conductivity characteristics of nanostructures using the semi-infinite boundary condition. Furthermore, calculations taking into consideration effects such as spin orbital interaction and noncollinear magnetism are also supported.
