Unter den im ersten Band dieses auf drei B nde projektierten Werks behandelten elementaren Anwendungen versteht der Autor Kollektivanregungen (Plasmonen, Phononen, Magnonen, Exzitonen) und die theorie des Elektrons als Quasiteilchen. Das Werk wendet sich an alle Naturwissenschaftler, die an einem tieferen Verst ndnis der theoretischen Grundlagen der Festk rperphysik interessiert sind.

A work that replaces the Comprehensive Index 1990 and its diskette update Comprehensive Index 1994 on the Landolt-Bornstein Directory Disk 1.1.

Sect. 1. 247 We have already stated that the subject of ionic conductivity can be properly regarded as one part of the wider study of imperfections, and it is on account of the coherence and unity of this wider subject that ionic conductors acquire their interest 4J. Thus the ideas of mobile interstitial atoms and vacant lattice sites are relevant to a wide range of phenomena; for example diffusion in solidsl, chemical reactions between two solids and between asolid and agas (e. g. tarnish- 3 ing reactions) 2, and annealing of radiation damage . There are, of course, imper- fections such as...
