Abstract
Electrical impedance measurements over the frequency range 10 Hz to 1 MHz are reported for fatty acid Langmuir - Blodgett (LB) films containing an organometallic tetrabutylammonium Ni(dmit) complex. Experiments were undertaken using both in-plane and out-of-plane electrode configurations. In the latter case, a relationship between the AC conductivity and frequency of the form was found, with n = 0.51 for a film containing a 0.31 molar fraction of fatty acid. This n value was found to decrease with an increase in the amount of the charge-transfer compound. For the in-plane AC measurements, the conductance of the sample was dominated by the DC conductivity of the LB film.
