Introduction to Surface and Superlattice Excitations [Paperback]

Cottam and Tilley provide an introduction to the properties of wave-like excitations associated with surfaces and interfaces. The emphasis is on acoustic, optic and magnetic excitations, and apart from one section on liquid surfaces, the text concentrates on solids. The important topic of superlattices is also discussed, in which the different kinds of excitation are considered from a unified point of view.

Throughout the book, the authors are careful to relate theory and experiment and all of the most important experimental techniques are described. The theoretical treatment assumes only a knowledge of undergraduate physics, except for Green function methods that are used in a few sections; these methods are developed in an appendix. The book also contains extensive references, enabling the reader to consult the research and review literature. Each of the main chapters contains problems to allow the reader to develop topics presented in the text.Cottam and Tilley provide an introduction to the properties of wave-like excitations associated with surfaces and interfaces. They emphasize acoustic, optic, and magnetic excitations and, apart from one section on liquid surfaces, the text focuses on solids. There have been considerable developments in the field since the first publication of the book, particularly in the understanding of the properties of superlattices and nonlinear effects, and this new edition deals with these in a comprehensive manner. Throughout the book the authors are careful to relate theory and experiment and describe all of the most important experimental techniques.BASIC CONCEPTS AND BULK PROPERTIES Introduction Bulk models and properties SINGLE-SURFACE, FILM AND RELATED EXCITATIONS Surface phonons and elastic modes Surface magnons Surface magnetostatic and Dipole-exchange modes Surface Polaritons Other Surface Excitations EXCITATIONS IN MULTILAYER STRUCTURES Nonmagnetic layered structures and superlattices Magnetic layered stl£
