Abstract
We report the dielectric and ac conductivity studies on the organic molecular ferroelectric, diisopropylammonium bromide polycrystalline sample. The frequency and temperature dependant real and imaginary parts of the impedance show two relaxations in the sample. The Nyquist plots exhibit two semicircles revealing both grain and grain boundary contributions to the resistance above Curie temperature. We find that the compound shows a non-Debye type relaxation behavior and the conductivity follows the semiconducting behavior. The conduction mechanism can be explained by the barrier hopping model. © 2014 Elsevier B.V. All rights reserved.
