Software - Prof. Klaus Hermann

    This page lists several software packages developed by members of the Fritz-Haber Institute with colleagues and offered to the scientific community for download. 


    • Balsac 
      Build and Analyze Lattices, Surfaces, And Clusters, by K. Hermann
      allows the construction, visualization, and interactive analysis of general crystal lattices including single crystal surfaces and of finite clusters, nanoparticles, and molecules
    • Balsac Gallery
       This gallery offers example illustrations from various research projects and publications using the Balsac (and other) software. The examples of each section are listed in alphabetical order. They are meant to support visual understanding of atomic structure and to stimulate new structure research.
    • LEEDpat
      by K. Hermann and M.A. Van Hove, HKBU Hong Kong
      is designed to analyze surface symmetry which can help to interpret experimentally observed LEED spot patterns for well-ordered surfaces, especially in the presence of superlattices.
    • oSSD
      by K. Hermann, M.A. Van Hove, HKBU Hong Kong, and P.R. Watson, Oregon State
      collects quantitative surface structures from experimental studies published between 1974 and 2004 when all "basic" structures have been explored. The database is an open source version of the NIST SSD package, version 5, which has been discontinued and will not be updated.
    • StoBe
      by K. Hermann and L.G.M. Pettersson, University Stockholm
      is a DFT program package to evaluate and analyze the geometric/electronic structure as well as spectroscopic and other properties of molecules and atom clusters.
