Homopolar bonds in Se-rich Ge-As-Se chalcogenide glasses

发布时间：2018-08-17 14:00

【摘要】：We have prepared three groups of Ge As Se glasses in which the Se content is 5.5 mol%, 10 mol%, and 20 mol%rich, respectively. We explored the possibility of suppressing the formation of the Ge Ge and As As homopolar bonds in the glasses. Thermal kinetics analysis indicated that the 5.5 mol% Se-rich Ge_(11.5)As_(24)Se_(64.5) glass exhibits the minimum fragility and thus is most stable against structural relaxation. Analysis of the Raman spectra of the glasses indicated that the Ge Ge and As As homopolar bonds could be almost completely suppressed in 20 mol% Se-rich Ge_(15)As_(14)Se_(71) glass.
