| Abstract: | Zinc-bismuth oxide glasses of 10-25 mol% of zinc oxide are prepared having thickness between 0.35-0.42 cm and diameter 0.60-0.95 cm. Physical properties such as density (d), molar volume (V), hopping distance (R), number of ions per cc (N) and polaron radius (rp) are also reported. Polaron radius is found around 1.85 Å which shows formation of small polarons. Measurements of de electrical conductivity are reported in the temperature range 443-573K. - Log σ versus 1/T and –log µ versus 1/T plots exhibited linearity. Hopping condition given by Holstein was applied. Polaron band-width (J) satisfies the inequality which shows adiabatic hopping conduction. The density of Fermi level and the density of localized states are found to be close to each other. |
