Abstract
Kinetics of optically-induced reaction between silver and Ge30S70 films was measured by monitoring the change in thickness of the undoped chalcogenide using a modified computer-controlled reflectivity technique. Silver concentration profiles during optically-induced solid state reaction were traced by the means of Rutherford backscattering spectroscopy (RBS). The composition of the Ge−S films was chosen to be Ge30S70 which is the most favourable for optically-induced solid state reaction, because it yields a homogeneous photodoped products. A new technique of step-by-step optically-induced dissolution and diffusion of Ag into Ge30S70 amorphous films, which has allowed to design films with exact silver concentration and to study their properties, is reported. The host Ge30S70 films were photodoped by consecutive dissolving a thin (≈20 nm) layer of silver, which resulted in homogeneous films of good optical quality. The silver concentration of the films ranged between 0 and 31.8 at. %. We have analysed in detail the influence of the silver doping in the host material on optical and thermal properties, and its structure. The photodoped films produced a single-phase homogeneous material with composition close to Ag2GeS3 in some of them. Results of all analytical techniques have helped to understand the processes taking place during silver photodissolution.
