Characterization of electronic and dielectric properties of anodic oxide films on bismuth by electrochemical impedance spectroscopy
Article Abstract:
Experiments were conducted to investigate a bismuth (Bi) oxide layer/electrolyte system. Electrochemical impedance spectroscopic analyses were performed. The dielectric properties of the potentiodynamically and potentiostatically Bi oxide films were described. These include donor concentration, critical potential and potential of anodic photocurrent onset. The data were compared using electrical circuit models. A sharp maximum was observed in the initial potential region.

Low-frequency dielectric investigations into the phase behavior of glycerol monoolein/water systems
Article Abstract:
The lyoropic and thermotropic phase behavior of glycerol monoolein/water liquid crystal systems was studied using dielectric spectroscopy. Results showed that the systems correspond to a parallel bulk capacitance and conductance in series with a Maxwell-Wagner blocking capacitance. An additional dispersion was also found to correspond with a series of resistance-capacitance circuit.
