Re: [QE-users] K-Point Grid for Larger Crystals (Stephen Zhang)

Hi there, Stephen. I do not know if I got your point, but the k-grid does not depend on the atomic basis. It depends on the crystal lattice itself. In QE you can define the Monkhorst-Pack k-point sampling by just setting the option automatic after the card K_POINTS (

[QE-users] K-Point Grid for Larger Crystals

2020-09-02 Thread Stephen Zhang
Hi Everyone, I just wanted to ask about the sort of k-point grids one would use for larger crystals (about 20 basis atoms). I've tried experimenting with different k-point densities with the crystal Co3Sn2S2 (7 basis atoms), and found that increasing the k-point grid density for scf calculations
