Description
Summary:The d.c. electrical property of the dithiolene complex, or bis(4-diethyannodithiobenzil)nickel (BDN) and stearyl alcohol (SA) mixed Langmuir-Blodgett films was investigated. The conductivity of the LB films as a function of the thickness of the films and the ratio of BDN:SA as well as the current versus voltage (I-V) characteristics have been measured. The conductivity of the LB films is about 3.5 x 10^sup -10^ S cm^sup -1^ which is less than the bulk conductivity of BDN, and the conductivity of the LB films is strongly influenced by BDN concentration. The I-V property of Al-LB films is governed by the thickness of oxide layers at the LB films with Al electrodes after Auger depth profiling analysis.[PUBLICATION ABSTRACT]
