Crystal face index

Crystallographic directions are lines linking nodes (atoms, ions or molecules) of a crystal. Similarly, crystallographic planes are planes linking nodes. Some directions and planes have a higher density of nodes; these dense planes have an influence on the behavior of the crystal: optical properties: in condensed … See more Miller indices form a notation system in crystallography for lattice planes in crystal (Bravais) lattices. In particular, a family of lattice planes of a given (direct) Bravais lattice is determined by three See more For the special case of simple cubic crystals, the lattice vectors are orthogonal and of equal length (usually denoted a), as are those of the reciprocal lattice. Thus, in this common case, … See more Ordinarily, Miller indices are always integers by definition, and this constraint is physically significant.

WebDec 21, 2024 · W. H. Miller suggested, in 1839, that each face of a crystal could be represented by the indices h, k and l, defined by h = XX, k = Y and l = ^. Figure 1.11. … WebCrystal faces are determined by the physical properties of a crystal, such as its structure and symmetry, while cleavage planes are created by the movement of chemical bonds. Additionally, each crystal face is associated with a Miller index, while cleavage planes are always associated with the same index.
