Kosevich A.M. The crystal lattice
2005. - 342 p.
The design of new materials is one of the most important tasks in promoting progress. To do this efficiently, the fundamental properties of the simplest forms of solids, i. е. , single crystals must be understood.
Not so long ago, materials science implied the development, experimental investigation, and theoretical description, of primarily construction materials with given elastic, plastic and resistive properties. In the last few decades, however, new materials, primarily crystalline, have begun to be viewed differently: as finished, self-contained devices. This is particularly true in electronics and optics.
To understand the properties of a crystal device it is not only necessary to know its structure but also the dynamics of physical processes occurring within it. For example, to describe the simplest displacement of the crystal atoms already requires a knowledge of the interatomic forces, which of course, entails a knowledge of the atomic positions.
