Crystal lattice planes

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 geometrical points. There are two classes of crystal lattices. When all of the lattice points are equivalent, it is called Bravais lattice. Otherwise, it is called non-Bravais lattice. WebThe lattice describes the repeat pattern; for diamond cubic crystals this lattice is "decorated" with a motifof two tetrahedrallybondedatoms in each primitive cell, separated by 1/4of the width of the unit cellin each dimension.[1]
