Structural characterization and electrical conductivity analysis of MoO3–SeO2–ZnO semiconducting glass nanocomposites

Influence of Gold Nano Particles on Dielectric Features A.C. Conductivity and Dielectric Breakdown Strength of PbO-B2O3-SeO2:Ho2O3 Glass Ceramics

“…As such a quite few numbers of studies were devoted to dielectric properties of SeO 2 glass systems containing low contents of SeO 2 . 6,[8][9][10][11][12] The dielectric studies including conductivity of the glasses containing larger amounts of SeO 2 were rarely investigated. It is obviously due to short-range order of this glass network.…”

Influence of Fe on Crystallization Behaviour and Electrical Conductivity of V2O5 ⋅ MoO3 ⋅ CdO ⋅ ZnO Glass Nanocomposite

“…But in this study, the density increases with respect to the concentration of Fe increases while V 2 O 5 modifies the glass network and leads to the compactness of the glass structure. The decrease in density with increasing V 2 O 5 level may be owing to an increase in non‐bridging oxygen caused by the change in volume concentration [31–32] . Density and molar volume show an inverse relation (Figure 1).…”

“…Density and molar volume show an inverse relation (Figure 1). The rise in molar volume caused by the addition of V 2 O 5 is attributable to an increasing number of non‐bridging oxygen [31–32] as well as different nanophases of V 2 O 5 , [33–44] dispersed in the glass matrix. The rate of change in molar volume is determined by the rates of change in density and molecular weight.…”

Electrical Conduction Mechanisms in Gd-Substituted WO3 Ceramics: Experimental and Theoretical Approaches

“…The increasing ratio of successful hopping with increasing frequency leads to a dispersion in conductivity, which can be clearly observed in the conductivity spectra. The dependency of AC conductivity σ(ω) on frequency can be explained by the modified Jonscher power law, which is σ false( ω false) = σ DC true[ 1 + true( ω ω normalH true) true] s where σ DC stands for DC conductivity, ω H is the hopping frequency, and s denotes the frequency exponent, which reveals the strength of polarizability. The inset of Figure shows the fitted frequency dependent log–log plot of conductivity at a particular temperature of 403 K for all of the compositions, which is further corroborated by the dielectric loss behavior results.…”
