“…This refers basically to the fact that more dipoles are polarized and follow the field orientation [26]. This finding implies that the prepared sample is a powerful candidate as an active channel or dielectric gates to be used in FET devices [27].Starting from their physical meanings, ε′() and ε″(ω) play a very important role in the ionic conduction process. The latter is controlled by four major types of polarization (interfacial, dipolar, electronic and ionic).…”

The development of a multifunctional material with variety in its properties is a powerful research project. The electrochemical properties of LiCo0.7Mn0.3O2 material have attracted our attention to search electrical characterization and the optical properties of this material. The synthesis of this compound is based on a solid state method. The X-ray powder diffraction analysis shows that the compound crystallizes in the hexagonal system with the R -3m space group. Moreover, the homogenous distribution of grain is revealed by the EDX study, thus the grain size is about 2.5 µm calculated from the scanning electron microscopy data. The band gap energy was established and seems to be equal to 1.88 eV which confirms the semiconductor character of this compound. Impedance spectroscopy was performed in the temperature ranging from 363 K to 473 K and frequency varying between 0.1 to 106Hz. The Nyquist plots confirm the presence of grains and grain boundary contribution instead of electrode polarization. The obtained conductivity properties indicates the semiconductor behavior of our compound, also it confirms its reliability for electrochemical application. Ac conductivity has been adjusted using the Jonsher power law, which allows us to confirm that the dc conductivity is thermally activated with activation energy of 400 meV and 500meV for 363–423 K, 423–473 K regions, respectively. Temperature dependence of the exponent s reveals that the conduction process is governed by the correlated barrier hopping model (CBH). Besides, the temperature coefficient of resistivity (TCR) affirmed that LiCo0.7Mn0.3O2 is a good candidate for bolometric applications.

“…The Cd-based dielectric exhibited higher capacitance than that for MAPbI 3 and frequency-dependent characteristics as well. 242 The facile-fabricated HOIP dielectric is expected to apply in high-performance and low-operating voltage field-effect transistors, especially in low operating frequency.…”
