The underlying principle of impedimetrie techniques is electrical impedance spectroscopy. These techniques are used in biochemical and environmental appUcations because of their sensitivity, however, with varying success. A wide variety of designs of the devices is known for the analysis of hiomaterials. " ...

We will distinguish various modes. The techniques most widely used in DSSCs are intensity modulated photocurrent spectroscopy (IMPS) which is, like IPCE, concerned with electron transport under short circuit conditions Intensity modulated photovoltage spectroscopy IMVS, which probes the competition between transport and recombination at open circuit and electrical impedance spectroscopy (EIS), which probes the bias-dependent electrical response, analogous to dark-current transients. Other variants, such as frequency-resolved transmittance, the frequency domain analogs of transient absorption, have been developed [50]. The techniques and...

When a range of frequencies is applied to the DUT, both El and ECI techniques are called spectroscopies, i.e., electrical impedance spectroscopy and electrochemical impedance spectroscopy. Electrochemical impedance spectroscopy (EIS) profiles, measured as a function of the interrogating frequency, can be presented by two popular plots complex plane impedance diagrams, sometimes called Nyquist or Cole-Cole plots, and Bode (I Z I and 6) plots (Fig. 2). As the impedance, Z, is composed of a real and an imaginary part, the Nyquist plot shows the relationship of the imaginary component of impedance, Z" (on the Y-axis), to the real component of the impedance, Z (on the X-axis), at each frequency. A diagonal line with a slope of 45° on a Nyquist plot represents the Warburg...

Polyaniline was used as hole injection material for polymer hght-emitting devices (PLED) spin-coated from a water-based polyaniline/poly-styrenesulfonate (PAni/PSS) dispersion. Data presented here were based on red, yellow, green, and blue LEPs. Depending on the applied bias voltages, the devices were studied by electrical impedance spectroscopy (EIS) in a wide frequency range. Experimental data could...

For the investigation of the properties of BLMs, electrical methods have been applied at the very beginning. In addition to the CV technique, other methods such as electrical impedance spectroscopy (EIS) have been applied. Shortly after the discovery of the BLM system, Hanai and Hay don reported the thickness measurement of a planar lipid bilayer using the impedance technique [1 - 3]. Their results are in accord with the value obtained on RBC, estimated by Fricke (see Eq. 1). The impedance technique, nowadays also known as EIS, has subsequently used by many others. The basis of the technique is that a small alternating current (AC) of known frequency and amplitude is applied to the system (e.g. a BLM). The resulting amplitude and phase difference that develop across the BLM are monitored. For a BLM of cross-sectional area (A), and thickness the ability of the BLM to conduct and to store electrical charges are described by the following ...
