Abstract:
Conductivity for an ultradispersed SnO$_2$ ceramic with an average crystallite size varied from 3 to 22 nm has been studied by voltammetry in fields of up to 2000 V/cm at room temperature. It was shown that current-voltage (I–V) characteristics are nonlinear at field strengths exceeding 200 V/cm. An analysis of the experimental data demonstrated that the characteristic distance between barriers that give rise to the nonlinearity in the I–V characteristics is $\sim$1 $\mu$m in all of the samples studied.
