WEBIn order to extract information about the atomic structure of a crystal, liquid or glass by diffraction, the wavelength of the probe must be compara-ble or smaller than the interatomic distances, which are typically a few Angstroms (˚ 10 10 m, or 10 1 nm). Tab. 1 illustrates the typical wavelengths

WEBJul 26, 2005 · The aim of this successful book is to describe and analyse peculiarities of classical and quantum dynamics of a crystal as a spatially periodic structure. In the second revised and updated edition, the author focuses on low-dimensional models of crystals and on superlattices.
WEB4 Dynamics of Atoms in Crystals. The physical properties of a solid can be roughly divided into those that are determined by the electrons and those that relate to the move ment of the atoms about their equilibrium positions.
WEBThe subject of lattice dynamics is the study of the vibrations of the atoms in a crystal. Whilst we intuitively understand that atoms must be vibrating within crystals – it is the natural interpretation of temperature – traditional crystallography often leads to the image of atoms being held in static positions through stiff chemical bonds.
