摘要：

A mechanism for the phenomenon of photodissolution of metals in amorphous chalcogenides is proposed which is based on the combined transport of ionic and electronic charge carriers during the photodissolution process. A parabolic law for the kinetics of this reaction is derived and the photoconductivity of the reaction product is the controlling factor for the rate. It is suggested that the site of the absorption of the actinic light is determined by the sign of the dominant electronic (photo) carriers in the reaction product.
