Expand a crystal structure into a supercell

Predefined supercell size option (ignored when dimensions is set)

Minimum total vacuum thickness in Å along vacuum_axis. Expands the cell and centers the slab if current vacuum is smaller. Typical for 2D materials: 15–20. Applied after the supercell transform.. Must be greater than 0 and at most 50.

Symmetry precision for structure analysis

Custom supercell dimensions [nx, ny, nz]. Overrides size when set. Use e.g. [5, 5, 1] for monolayers.

Lattice axis for vacuum padding (0=a, 1=b, 2=c). Default c.

Angle tolerance for symmetry finding in degrees (°)
