Crystal Structure Analysis

The fundamental assumption in the domain of continuum mechanics and physics is that matter is assumed to be continuous. This means, the matter is free of voids and spaces, the distribution is uniform throughout the system under consideration. Matters are composed of atoms that are grouped to form molecules, this grouping leads to molecular bonds which stack them together. This stacking may be completely compact or with minor spaces. The continuity approach assumes the stacking to be uniform without these spaces. An orderly and uniform arrangement of atoms, molecules, or ions in a crystalline material forms a crystal lattice or crystal structure. In the crystal structure, this is a systematic arrangement of molecules in a three-dimensional space. The study of analysis of crystal structure is essential to get information about the cleavage, electronic band structure, and optical transparency of matter. In crystallography, cleavage is the tendency of a crystalline material to undergo splitting along multiple crystallographic structural planes.
