WebAs a general rule, one should avoid using high symmetry points in the Brillouin zone as sampling points, because this would result in an inferior sampling quality at comparable numerical effort, compared to a similar number of off-axis k -points. WebPre-defined k-point sets for Crystalline calculations: hexagonal lattices The First Brillouin zone of a hexagonal lattice, with high symmetry k points marked. The above k-point …

WebAug 8, 2024 · Determine the points where two consecutive bisectors join, by writing down the equations of their straight lines and making them equal. The points where bisectors cross are your high symmetry points. And this process, repeated for all pairs of vectors in point 2, give you the first Brillouin zone. I got the following: WebThe k-points are given as [MonkhorstPack]: ∑ i = 1, 2, 3 2 n i − N i − 1 2 N i b i, where n i = 1, 2,..., N i, size = ( N 1, N 2, N 3) and the b i ’s are reciprocal lattice vectors. ase.dft.kpoints.get_monkhorst_pack_size_and_offset(kpts) [source] Find Monkhorst-Pack size and offset. Returns (size, offset), where: list of tom gates books
