Abstract
The effect of replacing vanadium by Cu2+ ion on the dc-electrical conductivity (σ) and I–V characteristics of (V2O5) 0.7 (GeO2) 0.3 glass has been investigated at different temperatures. The conductivity value increases with increasing the concentration of Cu2+. The electrical conduction is interpreted on the basis of electrons hopping from reduced to unreduced vanadium and/or cupper ions. The I–V characteristic curves showed three regions of conduction, namely, high resistance state (OFF-state), turnover point with zero ...
