Abstract
The electrical transport properties of stearic acid(SA) LB films on various substrates were investigated. The ohmic characteristics for a metal/SA/Cr structure directly showed the existence of short circuits in these LB films. The V-I characteristic for a metal/SA/Al structure was found to be tunneling conduction through an insulating oxide layer on the Al surface. The V-I characteristic for a metal/SA/semiconductor structure was similar to that for a metal/semiconductor Schottky junction. These results confirm the existence of short circuits in SA LB films on any kind of substrate. The consistency of the author's experimental results with those previously reported shows that the existence of short circuits is a general phenomenon, not limited to the author's experiments.
