Electronic Defect States In Alkali Halides

The radiative properties of the electron-hole pairs and excitons are modified owing to the drastic change in the structure of the electromagnetic-field modes.This book is the first to give a comprehensive account of the theory of semiconductor cavity quantum electrodynamics for such systems in the weak-coupling and strong-coupling regimes. Recent advances in semiconductor technology have made it possible to fabricate microcavity structures in which both photon fields and electron-hole pairs (or excitons) are confined in a small volume comparable to their wavelength.

1). Since the subject is far from being settled, different opinions on specific aspects of the Mott transition still persist.

Only since processes like IBAD and RABiTS TM were invented have film deposition techniques also become important for energy technology.In order to produce suitable conductors with material properties which meet the challenge imposed by energy technology, detailed understanding of the phase formation and physical properties of the high temperature super conductors is necessary.

The production of multi layered thin films with sufficient reliability is a key technology for device fabrication in micro electronics.In these alloy systems, one can obtain a sample thickness of several centime ters..
