Beschreibung (Kurztext)
In crystals as diverse as sodium chloride, silicon dioxide, sold xenon, pyrene, arsenic triselenide, and silver chloride, the fundamental electronic excitation (exciton) is localized within its own lattice distortion field very shortly after its creation. This book discusses the structure if the self-trapped exciton (STE) and its evolution along the path of its return to the ground state or to a defect state of crytal. A comprehensive review of experiments on STEs in a wide range of materials has been assembled, including extensive tables of data. Throughout, emphasis is given to the basic physics underlying various manifestations of self-trapping. The role of the spontaneous symmetry-breaking or "off-center" relaxation in STE structure is examined thoroughly, and leads naturally to the subject of lattice defect formation as a product of STE relaxation.
The theory of STEs is developed from a localized, atomistic perspective using self-onsistent methods adapted from the theory of defects in solids. At this time of rapid progress in STEs, researchers will welcome the first monograph dedicaded solely to this topic.
Das Buch Self-Trapped Excitons beschreibt die Struktur und Entwicklung von selbstanlagernden Excitons in einer großen Variationsbreite von Materialien. Es enthält eine Diskussion der Theorie, eine umfassende Übersicht von Experimenten und ausführliche Datentabellen. Zu einer Zeit des rapiden Fortschritts auf diesem Gebiet wird die erste Monographie, die sich nur dem Thema der selbstanlagernden Excitons widmet, von Forschern begrüßt werden.

Self-Trapped Excitons
discusses the structure and evolution of the self-trapped exciton (STE) in a wide range of materials. It includes a comprehensive review of experiments and extensive tables of data. Emphasis is given throughout to the unity of the basic physics underlying various manifestations of self-trapping, with the theory being developed from a localized, atomistic perspective. The topics treated in detail in relation to STE relaxation include spontaneous symmetry breaking, lattice defect formation, radiation damage, and electronic sputtering.
