Designing heavy metal oxide glasses with threshold properties from network rigidity
Shibalik Chakraborty, P. Boolchand, M. Malki +1
Here we show that a new class of glasses composed of heavy metal oxides involving transition metals (VO5-TeO), can surprisingly be designed from ve…
Direct evidence for a characteristic dynamic lengthscale in the intermediate phase of glasses
M. Micoulaut, M. Malki
AC conductivity spectra of xAgI-(1-x)AgPO fast ion conducting glasses spanning the flexible, intermediate (isostatically rigid) and stressed rigid phases are analyzed. The resc…
Fast-ion conduction and flexibility and rigidity of solid electrolyte glasses
M. Micoulaut, M. Malki, D. I. Novita +1
Electrical conductivity of dry, slow cooled (AgPO)(AgI) glasses is examined as a function of temperature, frequency and glass composition. From these data compositi…
Fast-ion conduction and flexibility of glassy networks
Deassy I. Novita, P. Boolchand, M. Malki +1
We observe two thresholds in the variations of electrical conductivity of dry solid electrolyte (AgI)x(AgPO3)1-x glasses, when the AgI additive concentration x increases to 9.5% an…
Correlation between floppy to rigid transitions and non-Arrhenius conductivity in glasses
M. Malki, M. micoulaut, F. Chaimbault +1
Non-Arrhenius behaviour and fast increase of the ionic conductivity is observed for a number of potassium silicate glasses with potassium oxide concentration lar…
Raman thresholds and rigid to floppy transitions in calcium silicate glasses
M. Micoulaut, M. Malki, P. Simon +1
Alkaline earth silicate glasses exhibit a well marked threshold in Raman lineshapes which can be related to the onset of network rigidity as the concentration of…
