Study of glass transition kinetics of As2S3 and As2Se3 by ultrafast differential scanning calorimetry

         

摘要

Ultrafast differential scanning calorimetry (DSC) was employed to investigate the glass transition kinetics of As2S3 and As2Se3.By using the Arrhenius method,a fragility index of ~ 22 can be estimated in both As2S3 and As2Se3.However,when the scanning rate is more than 200 K.s 1,non-Arrhenius behavior can be observed in such "strong" liquids where the Vogel-Fulcher method is more accurate to describe the glass transition kinetics.The fragilities of As2S3 and As2Se3 glasses are thus extrapolated as 28.3+1.94 and 23.7± 1.80,respectively.This indicates that,As2Se3 glass has a better structural stability and it is a better candidate for device applications.
