GOBZ

GOBZ
is an option to decide, if a Brillouin zone is plotted.

DetailsDetails

  • GTVoronoiCell allows to construct Brillouin zones. The Brillouin zone can be shown together with the calculated Fermi surface.
  • Typical values for GOBZ are:
  • Truethe Brillouin zone is plotted
    Falsethe Brillouin zone is not plotted
  • This option is used by: GTFermiSurface
