Michael G. Cottam - Böcker

In recent years there have been exciting developments in techniques for producing multilayered structures of different materials, often with thicknesses as small as only a few atomic layers. These artificial structures, known as superlattices, can either be grown with the layers stacked in an alternating fashion (the periodic case) or according to some other well-defined mathematical rule (the quasiperiodic case). This book describes research on the excitations (or wave-like behavior) of these materials, with emphasis on how the material properties are coupled to photons (the quanta of the light or the electromagnetic radiation) to produce "mixed� waves called polaritons.�Clear and comprehensive account of polaritons in multilayered structures�Covers both periodic and quasiperiodic superlattices�Careful attention to theoretical developments and tools�Invaluable guide for researchers in this field�Shows developments from the basics to advanced topics

An introduction to the properties of wavelike 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.

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.
