Photocarrier Motion in Ionic Crystals,otocarriers, they are self-trapped and become immobile in a short time of the order of 10. s. In this case, little current is carried by photocarriers within their lifetimes and the material is nonphotoconductive with regard to the respective carriers.

The Exciton and Excitonic Molecule in Cuprous Halides,ions. The CuCl crystal is the first case where the excitonic molecule (EM) has been found to be created through exciton-exciton collisions. The EM is annihilated radiatively leaving an exciton behind. It can also be created directly through two-photon excitation with giant oscillator strength. Raman

Theory of Excitons in Phonon Fields,ly periodic field of a rigid crystal, but the real crystal lattice is deformable and vibrating. The lattice vibrations cause a spatially and temporally fluctuating potential for the exciton. The . fluctuation gives rise to scattering and momentary localization of the exciton, as reflected in the bro

Excitons in Condensed Rare Gases,orough investigations can be made both experimentally and theoretically. Furthermore, there are specific features in the properties of condensed rare gases. First, the rare-gas atoms have closed electron shells and do not form stable diatomic molecules, so consequently only a small cohesive energy d

Excitons and Their Interactions with Phonons and External Fields in Thallous Halides,nly interesting materials in many respects for the study of the excitonic molecule (EM) and exciton-phonon coupling. In this chapter we introduce other ionic crystals important for the study of excitons, that is thallous halides [7.1].

Photocarrier Motion in Ionic Crystals,, it does not carry charges as an electric current in an externally applied electric field. If the energy of the incident light is higher than the ionization threshold energy of the exciton, equal numbers of free electrons and holes can be formed as a result of the ionization of excitons. The excite

Excitons and Phonon Couplings in Quasi-One-Dimensional Crystals,t of an excited electronic state and its phonon coupling. In 3-d crystals, one finds almost always an excited electronic state in the form of a Wannier or a Frenkel exciton. The former case is found in typical ionic crystals and semiconductors and the latter in molecular crystals. In quasi-one-dimen
