Only reliable for band-structure calculations
Web29 de abr. de 2024 · If you are interested in how bands are calculated in DFT for very big systems (for small systems, you can imagine how bands tend to look continuous due to many K points), it's a matter of discretion. Some calculations are done at just one K point - the rest is 'folded' into the 1st BZ - You can look up 'Brillouin zone folding'. WebFor band structure calculations, the wrong symmetry can cause the choice of \(\mathbf{k}\) path to be wrong if using automated scripts to generate the path for you. For example, the structure in CONTCAR could be very close to a hexagonal or tetragonal unit cell, but there could be just enough difference in the lattice constants for the cell to be …
