Fabrication and structural reconfiguration of nanostructured As-S chalcogenide films via gold nanoparticles and laser processing

Abstract

Chalcogenide glasses and nanostructured thin films are promising materials for infrared photonics, optical data storage, and reconfigurable devices due to their high optical nonlinearity and pronounced photo-induced structural response. Arsenic sulfide (As-S) systems are widely used as a model platform for studying structure-property relationships under external stimuli. However, the mechanisms governing crystallization, light-induced transformations, and mass transport remain incompletely understood.
