| Summary: | Nonlinear current-voltage and coulomb-voltage characteristics with a hysteresis loop, which is peculiar to ferroelectrics, were observed in the boundary layers of individual saturated organic acids and oleic acid which have a domain structure and also an anomalously high conductivity which corresponds, in its order of magnitude, to the lower conductivity limit for metals. These effects are related with the formation of a volume space charge and by the cording of the current (formation of conductivity channels). The electrical properties of the boundary layers change in relation to the thickness: for subcritical thicknesses Ohm's Law is obeyed but for larger thicknesses strong field effects are observed. The thickness at which the system changes into the nonconducting stage has meaning as a physical characteristic of the system. |
