WebApr 1, 2024 · Thus to define a crystal structure. We first define a lattice - a set of regularly laid out points; We then define the basis - a list of atom types and positions and offsets; We then associate an identical basis with every lattice point; Thus for a given lattice we can have any number of bases, and each basis can contain any number of atoms.
