Mihai Popescu,Florinel Sava,A. Lőrinczi,Gabriel Socol,Ion N. Mihailescu,A. Tomescu,Cristian E. Simion +6 more
TL;DR: Amorphous SnSe2 films were prepared by pulsed laser deposition (PLD) from solid polycrystalline targets as discussed by the authors, and the atomic scale structure has been revealed by X-ray diffraction.

Possible mechanism of Ag photodiffusion in a-As2S3 thin films
Abstract: Monitoring the silver photodiffusion in thin amorphous As2S3 film is addressed with a new experimental setup. A possible photo-diffusion mechanism of silver into the a-As2S3 thin film under green laser diode light (l1⁄4 532 nm) irradiation is proposed. The proposed mechanism is based on a gradual filling of the structural voids existing in the network of the thin chalcogenide layer. This mechanism is supported by XRD measurements, optical absorption, and modeling data.

Crystalline–amorphous and amorphous–amorphous transitions in phase-change materials
TL;DR: The transition from the crystalline state to amorphous state and back has been studied in the particular case of the GeSb2Te4 phase-change material by a computer simulation procedure as discussed by the authors.
