Phonon

The Phonon module computes temperature- dependent vibrational properties of solids, surfaces, interfaces, molecules and clusters represented in a periodic model.

Computational characteristics

  • Automatic detection and use of any space-group symmetry
  • Fully automatic determination of supercell and all necessary atomic displacements
  • Fully automated setup, execution, and processing of VASP jobs
  • Forces computed with VASP 4.6 or 5.2 with any of available functionals
    • including GGA+U, hybrid functionals, and fully relativistic Hamiltonians)
  • Partial freezing of atoms: obtain vibrational modes of molecules on surfaces
  • Works with transition state search: vibrational partition functions for reaction and diffusion rates (Eyring’s transition state theory)
  • Restart capabilities in case of hardware or communication failures

Required MedeA modules

  • Basic MedeA environment
  • MedeA VASP 4.6 or 5.2
  • Job Server and Task Servers
