Abstract

Surface activity of solution deposited (SD) amorphous films of $As_2S_3$ has been investigated. Silver and copper are readily deposited on such films from appropriate aqueous ionic solutions. The metals diffuse into the films upon irradiation with energetic photons. Structure and properties of SD films have been investigated using electron microscopy, optical spectroscopy and differential scanning calorimetry.The amorphous films tend to crystallize upon metal diffusion. The stability of amorphous films,the deposition of metals on their active surfaces and the photoinduced diffusion may all be attributed to the presence or production of charged defects in amorphous chalcogenide films.
