WebAug 5, 2014 · My q-points are generated like this: First, I use the MP method to generate 20x20x20 uniform q-points, and then I delete the q-points outside the first Brillouin zone (for FCC lattice, the Brillouin zone is not cubic), then the number of q-points will be reduced to be 4000. I wish to reduce the q-points to be the irreducible k-points according ... WebThe remedy in this case is provided by using a denser set of 8125 irreducible k-points (upper right panel of Figure 7) rather than only 550 irreducible k-points (upper left panel of Figure 7). We note here that the study of realistic materials at finite temperature requires to take all physical contributions to the free energy into account ...

WebApr 6, 2016 · Increasing the density of k-points in the Brillouin zone can increase the accuracy of the calculation, but the cost of approximating the integral typically scales linearly with the number of symmetrically irreducible k-points (i.e. the largest subset of k-points for which no two k-points in the subset are symmetrically equivalent). To minimize ... WebThe number of k-points to be used for this sampling, in the full Brillouin zone, is inversely proportional to the unit cell volume, but may also vary a lot from system to system. As a … early range training osrs

WebSep 22, 2024 · There are three choices for the k sampling in terms of the distance between two k points. Very fine [0.15 1/A] Fine [0.2 1/A] Normal [0.3 1/A] Very often, you can just take the fine option to obtain reliable results.

For example, the bigger the unit cell is, the fewer points are generally needed. Please note, that it is only necessary to sample the directions in which the crystal is periodic. A carbon nanotube, for example, only requires a large k ... early railways
