AC conductivity and dielectric characterization of synthesized p-N,N dimethylaminobenzylidenemalononitrile (DBM) organic dye

► DBM compound is of the type donor-phenyl-acceptor (D-ph-A). ► Both capacitance and loss tangent are found to decrease by increasing frequency. ► Both capacitance and loss tangent are found to increase by increasing temperature. ► Single polaron hopping mechanism is the dominating conduction in DBM compound.
