Analysis of current‐voltage characteristics of metal‐insulator composite films (original) (raw)

Journal of Applied Physics, 1986

Abstract

We present a method for analyzing current-voltage relationships to obtain information on the dominant conduction mechanisms. The method is based on the analysis of the derivative of the logarithmic conductivity with respect to inverse applied electrical field. To illustrate the method we apply it to the study of Co-Al2O3 and Au-Al2O3 composite films. The former material displays space-charge-limited conduction, which is due to a high density of trap states in the oxide matrix. On the other hand, Au-Al2O3 shows evidence of percolation and tunneling between metal particles.
