Electrical characterization of the grain-boundary region of SnO2 varistors
(Trans Tech Publications Ltd, 2006)
The effect of Co, Cr and Nb on the electrical properties of the grain boundaries of SnO2-based varistors was investigated. The powders were prepared by the method of evaporation and decomposition of solutions and suspensions. ...
Temperature dependence of fractal dimension of grain boundary region in SnO2 based ceramics
(Springer, New York, 2006)
Fractal dimensions of grain boundary region in doped SnO2 ceramics were determined based on previously derived fractal model. This model considers fractal dimension as a measure of homogeneity of distribution of charge ...
