Variable Range Hopping Conduction

The formation and electrical properties of high surface area NiO/Al2O3 nanocomposite materials with composition ranging from 5 to 30% w/w have been studied. The temperature dependence of the DC electrical resistivity was monitored in the temperature range 350–600 K. The results revealed correlation between electrical resistivity and textural properties. The conductivity results were discussed in terms of variable-range-hopping mechanism.

The Difference

Single crystals of cobalt oxyborates Co3O2BO3 and Co3-xFexO2BO3 were synthesized. The crystal structure and electric properties were investigated. The difference in the electrical resistivity behaviors was found. For parent Co3O2BO3 nor simple activation law, nor Mott variable range hopping (VRH) are acquirable to describe the experimental data in wide temperature region. In contrast for Co3-xFex O2BO3 Mott’s variable-range hopping conductivity clearly dominates.
