heal.abstract The Raman scattering spectra of two ternary floppy (Z < 2.4) Ge-As-S chalcogenide glasses have been measured over temperatures ranging from 20 K, through the respective glass transition temperature Tg and up to a temperature close to melting point. Additional Differential Scanning Calorimetry (DSC) measurements have been carried out in these glasses at high temperatures from which values of Tg have been determined. The purpose of this work is twofold: (i) to study, through the Raman spectra and in particular the Boson peak (BP), critical phenomena around the Tg and make comparisons with the results obtained by DSC, and (ii) to make overall comparisons of the present Raman results and conclusions with those reported in a previous Raman study [Boulmetis et al, J. Optoelectron. Adv. Mater. 7, 1209 (2005)] on rigid (Z > 2.4) Ge-As-S glasses. It has been found that the study of the Boson peak is a reliable technique for predicting and determining the onset of the transition to the supercooled liquid phase in floppy chalcogenide glasses. en
