Glass transition in As10Se90 chalcogenide glass: A kinetic study

Glass transition kinetics and crystallization mechanism in Se90Cd8Bi2 and Se90Cd6Bi4 chalcogenide glasses

“…Studying the glass transition kinetics, from the dependence of T g on heating rate, was carried out by several researchers [2][3][4][5][6][7][8]. In all these studies, the recorded T g is found to increase with increasing heating rate.…”

“…Finally, Kissinger relation [29] has been widely [2][3][4][5][6][7][8] used to describe the variation of the glass transition temperature with the heating rate ˇ. This relation was originally developed for crystallization processes to evaluate the crystallization activation energy.…”

“…A great deal of these researches has been focused on studying the glass transition kinetics [2][3][4][5][6][7][8] and the crystallization mechanism [9][10][11][12][13][14][15]. The related parameters of these transformations are important for better understanding of the physics of these materials and for determination of the useful range of operating temperature at which these materials may be utilized in a specific technological application before crystallization takes place [9,14].…”

Dielectric relaxation processes in stoichiometric Ge:Sb:Te amorphous films

“…On the other hand, in As 10 Se 90 chalcogenide glass, according to differential scanning calorimetry measurements, the possibility of having two relaxation processes, α and β types has been pointed out [22]. In Se 70 Te 28 Zn 2 [23,Fig.…”

“…[6] and [15]) and for AsSe (Refs. [20] and [22]). Ge 2 Sb 2 Te 5 is a material which can reversibly transform from amorphous to crystalline phases on which the phase-change recording application is based.…”
