Photoinduced Changes of Structure and Properties of Amorpous Binary and Ternary Chalcogenides
Abstract
New results obtained recently in the study of isotropic photoinduced effects are described and discussed. The isotropic effects in binary systems such as As-S, Sb-S and in some ternary systems (As-Ga-S, As-Sb-S, Ge-Sb-S, Ge-Ga-S) are connected with the changes of bond statistics and short range order not only in the case of irreversible changes but also in the case of reversible ones. Similar changes of optical properties and the structure that are produced by photodarkening can be obtained by change of stoichiometry of a film. It supports the idea that the exposure of such systems creates bonds among like atoms by photolytic reactions. The exposure influences also index of refraction. The present or potential applications of isotropic photoinduced effects for production of optical and optoelectronics elements and optical storage are also described and discussed.
