内容简介：
Modulated crystals have been intensively investigated over the past several years, and it is now evident that an understanding of their crystallography and microstructure is fundamental to the elucidation of the physical properties and phase transitions in these materials. This book brings together the crystallographic descriptions and experimental methods for the structural and microstructural analysis of modulated crystals, as described by well-known researchers in the various areas. The emphasis is on charge density wave modulations, and the detailed analysis of the prototypical NbTe4/TaTe4 system gives practical applications of the methods. Scanning tunnelling microscopy is a technique that provides insights into atomic scale details of the modulations' structures and a chapter on this method is included.
