Abstract :
Thin films from Ge-S-AgI system with various amount of AgI prepared by pulsed laser deposition and vacuum thermal evaporation method have been studied. The films are analysed with respect to their morphology, structure and roughness. The optical properties are investigated as a function of the composition and preparation method.
