## Abstract Four Ge~2~Sb~2~Te~5~ thin films were prepared by pulsed laser deposition (PLD) at 58, 100, 140, and 190βmJ/pulse laser energy, respectively. The influence of laser energy on the crystallization of Ge~2~Sb~2~Te~5~ was investigated. The result shows that laser energy has evident effect on
## Abstract Amorphous thin films of SnSe~2~ and Ge~2~Sb~2~Te~5~ doped by different amount of silver (0.1, 0.2, 0.5 and 1 Ag atoms per formula unit) have been prepared by pulsed laser deposition (PLD) starting from solid polycrystalline targets. The films were investigated by Xβray diffraction (XRD)
