“…This increase in free volume would facilitate the motion of ionic charge [18]. The existence of two regions in the conductivity vs temperature plots has been observed in a number of polymer electrolytes [19,20]. The DC conductivity (σ) as per Arrhenius relation can be expressed as…”

Ion-conducting solid polymer blend electrolytes based on polyvinyl chloride (PVC)/poly methyl methacrylate (PMMA) complexed with sodium perchlorate (NaClO 4 ) were prepared in various concentrations by solution cast technique. The features of complexation of the electrolytes were studied by X-ray diffraction (XRD) and Fourier transform infrared (FTIR) spectroscopy. DC conductivity of the films was measured in the temperature range 303-398 K. Transference number measurements were carried out to investigate the nature of charge transport in the polymer blend electrolyte system. The electrical conductivity increased with increasing dopant concentration, which is attributed to the formation of charge transfer complexes. The polymer complexes exhibited Arrhenius type dependence of conductivity with temperature. In the temperature range studied, two regions with different activation energies were observed. Transference number data showed that the charge transport in this system is predominantly due to ions. Optical properties like absorption edge, direct band gap, and indirect band gap were estimated for pure and doped films from their optical absorption spectra in the wavelength region 200-600 nm. It was found that the energy gap and band edge values shifted to lower energies on doping with NaClO 4 salt.

“…Zor [43] also found the space-charge-limited currents as the dominant conduction mechanism ion evaporated polyethylene films, having thicknesses in the range from 1200 to 4200 A and sandwiched between Cu and A1 electrodes. Some influence of space-charge-limited currents above 300 K was found in the current-voltage characteristics of vacuum-deposited polycrystalline Pterphenyl films by Staryga and Swiatek [41]. Some electrical properties of the polymers discussed above are presented in Table 1.…”

“…They also made a rough estimate of the density of traps and its temperature dependence. The electrical conductivity of thin polycrystalline P-terphenyl films was investigated as a function of temperature, electric field, and film thickness by Staryga and Swiatek [41]. They interpreted their data in terms of a hopping process between localized sites over potential barriers lowered by the electric field according to the Poole-Prenkel formula as shown in Fig.…”

“…For instance, in the 3D model of Jonscher [30], the probability of the charge carrier to escape not only in the direction of the applied field, but in all directions was considered and a was found to be − 1 2 . This value of the exponent was also found when a de-trapped charge carrier was assumed to be captured by the first trapping centre [31]. If the de-trapped carriers travel a distance proportional to the applied field (Ohm's law) as in the crystalline (or semi-crystalline) semiconductors, Equation (9) becomes the widely used Poole-Frenkel equation with the exponent a = 1 [30,32].…”

Hydrogenated amorphous silicon nitride-based heterojunction pin diode was electroformed under sufficiently high forward bias stress leading to its instant nanocrystallization at room temperature. In order to investigate the origin of the accompanying bright visible light emission, current-voltage and electroluminescence (EL) characteristics of the electroformed diode were scanned over temperature. Electrical transport mechanism was analysed in the low, medium and high electric field regimes. Temperature and field dependence of thermal activation energy were discussed. EL characteristics were studied using the spectral energy distribution and the injection current dependence of its intensity. Thermal quenching data of EL and photoluminescence intensities were compared. Finally, the relationship between the electrical transport and luminescence phenomena was attempted to be interpreted within the frame of a self-consistent model.
