- | Copper has a fcc crystal structure. The unit cell is containing only one atom, thus the Cu_bulk.bas file contains only one atom: | ||
- | 1 | ||
- | 29 0.00000 0.00000 0.00000 | ||
- | The unit cell prepared, so [1,1,0] crystallography axis is equal to x axis is written in the Cu_bulk.lvs: | ||
- | 0.70711 0.00000 0.00000 | ||
- | 0.35355 0.61237 0.00000 | ||
- | 0.35355 0.20412 0.57735 | ||
- | And the 8x8x8 Monkhorst-Pack grid is via Oh symmetry of the cell reduced to the 105 k-points: | ||
