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

(As2S3)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 (As2S3)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.
