Raman and AFM studies of (As2S3)0.45(SbSI)0.55 thin films and bulk glass

Abstract (As 2 S 3 ) 0.45 (SbSI) 0.55 thin films were studied by Raman spectroscopy and atomic force microscopy. Laser-induced crystallization of SbSI crystallites from the amorphous (As 2 S 3 ) 0.45 (SbSI) 0.55 thin films was observed in micro-Raman measurements as a result of local laser beam heating. The dependence of the observed effect on the laser power and the film pre-heating duration is discussed. No such effects were observed for bulk glasses with a similar composition.
