“…Such significant change in the electrical conductivity at room temperature for CNT additive glass composites may be attributed to effect of highly conducting CNT. In Se 85 Te 10 Ag 5 glassy alloy the conductivity as reported by researchers [4,5,18] are due to Ag þ ion and somewhere reported mixed [10] i.e. ionic and electronic conductivity mechanism is suggested in case of Ag and Cu containing chalcogenide.…”
