- Keating_Model abstract "The Keating Model is a model introduced by British theoretical physicist Patrick N. Keating in 1966 to describe the forces induced on neighboring atoms when one atom is moved in a solid.It is most often applied to the forces on first- and second-nearest neighboring atoms which arise when an atom is moved in tetrahedrally-bonded solids, such as diamond, silicon, germanium, and a number of other covalent crystals with the diamond or zinc blende structures.Crystalline solids generally consist of an ordered array of interconnected atoms, generated by repetition of a unit cell in three dimensions, and are of two extreme types; ionic crystals, and covalent crystals, with others which are intermediate: partly ionic and partly covalent. Ionic crystals are made up of quite different ions, such as Na+ and Cl− in common salt, for example, while covalent crystals such as diamond are made up of atoms which share electrons in a covalent bond.In either case, there are attractive and repulsive forces which resist moving an atom/ion or a set of them from their equilibrium positions, thus giving solids their rigidity against compressive, tensile, and shear stresses. The nature and strength of these forces is important for the scientific understanding of solids since they determine the way the solid responds to these stresses (elastic constants), the velocity of sound waves in it, its infra-red absorption, and many other properties.".
