Crystallographic zone
The translational invariance of a crystal lattice is described by a set of unit cell, direct lattice basis vectors (contravariant or polar) called a, b, and c, or equivalently by the lattice parameters, i.e. the magnitudes of the vectors, called a, b and c, and the angles between them, called α (between b and c), β (between c and a), and γ (between a and b). Direct lattice vectors have components measured in distance units, like meters (m) or angstroms (Å). WebThese are referred to as crystallographic zones and they represent a direction in the crystal lattice. Zone axis concept Only in the isometric systems are the same integers used to relater the perpendicular to a family of planes ( hkl) to the directions [ uvw ].
