WebThe method of Monkhorst and Pack for special-point generation is explained and an example of its application to the fcc lattice is discussed. Several convergence tests performed with the PWSCF code are presented. The problem of sampling the Fermi surface in metallic systems is briefly discussed. WebThe origin of the Monkhorst-Pack grid may be offset by a vector from the origin of the Brillouin zone. If no k-points are specified, the default will be a Monkhorst-Pack grid with …
WebA Monkhorst-Pack grid that is always shifted to be centered on the gamma point (line 3 starts with “G” in the KPOINTS file). The shift will always result in one k point being on the gamma point.
