Global geometry optimization of small silicon clusters at the level of density functional theory

  • Bernd Hartke
Regular article


By an application to small silicon clusters SiN (with N = 4,5,7,10) it is shown that truly global geometry optimization on an ab initio or density functional theory level can be achieved, at a computational cost of approximately 1–5 traditional local optimization runs (depending on cluster size). This extends global optimization from the limited area of empirical potentials into the realm of ab initio quantum chemistry.
