Crystal basis
WebHeck, basis vectors in crystallography aren't even linearly independent. You can have a 3D crystal structure where the unit cell contains a large number of atoms. Then you have way more than 3 basis vectors, who can't possibly be linearly independent. Basis vector in crystallography ≠ basis vector in linear algebra. – Lagerbaer May 7, 2013 at 13:58 WebSep 7, 2024 · Crystal is a three dimensional periodic array of atoms. Crystal lattice is the geometrical pattern of the crystal, where all the atom sites are represented by the …
