“…On considering the dependence of ε´ with temperature, the results show that at lower frequencies the change is more prominent in the low temperature range. However, at high frequency range the change is of negligible order [31]. This can also be interpreted on the basis of MaxwellWagner theory.…”

“…4 The dielectric relaxation spectroscopy (DRS) gives evidence about the orientation and translation adjustment of the mobile charges presented in the dielectric medium. [5][6][7][8][9] The energy transferred to the dielectric material is not only a function of the applied electric field but also depends on the physical properties of material. 8,9 The contributions of dielectric polarization components such as electronic, ionic and orientational polarization are responsible for the variation of the dielectric constant values.…”

The Sb 2 S 3 bulk material was used for next-generation anode for lithium-ion batteries. Alternative current (AC) conductivity, dielectric properties and electric modulus of Sb 2 S 3 have been investigated. The measurements were carried out in the frequency range from 40 Hz to 5 MHz and temperature range from 293 K to 453 K. The direct current (DC) conductivity, r DC , shows an activated behavior and the calculated activation energy is 0.50 eV. The AC conductivity, r AC , was found to increase with the increase of temperature and frequency. The conduction mechanism of r AC was controlled by the correlated barrier hopping model. The behavior of the dielectric constant, e¢, and dielectric loss index, e¢¢, reveal that the polarization process of Sb 2 S 3 is dipolar in nature. The behavior of both e¢ and e¢¢ reveals that bulk Sb 2 S 3 has no ferroelectric or piezoelectric phase transition. The dielectric modulus, M, gives a simple method for evaluating the activation energy of the dielectric relaxation. The calculated activation energy from M is 0.045 eV.

Calcium titanate nanopowder doped with high content (1 M%) of iron was synthesized using simple sol-gel method. The four obtained samples were post-sintered at 100, 500, 900, and 1250°C to get soft agglomerates of nanocrystalline perovskites, which were deagglomerated by wet milling process using ethanol as a medium. The general stoichiometric formula for iron-doped CaTiO 3 was symbolized as CaTi 1-x Fe x O 3-d . The crystallographic structure of perovskites was found to be orthorhombic for all the four samples. The real and imaginary parts of the impedance values of sintered samples as a function of frequency were obtained using complex impedance spectroscopy. All the instrumental parameters were calibrated before initiating the measurements. The frequency range was set between 0.01 Hz and 1 MHz, and AC bias voltage was maintained at 50 mV. The objective of this work was to find the economical relevance of pioneering materials for electronic applications such as hydrogen production in fuel cells, solar plant, ferroelectric memory devices, microwave resonators, and sensible membranes as they are cheap and readily available, and can be prepared using controllable synthesis in a commercial laboratory.
