“…Complex impedance spectroscopy techniques can be employed to circumvent the restrictions in frequency-dependent dielectric constant and dielectric loss [29][30][31][32][33][34]. To understand the dielectric behavior and electrical conductivity of materials, the Cole-Cole plot is commonly used in impedance spectroscopic studies to determine the variation among various parameters such as permittivity, impedance, electric modulus, and tangent loss as a function of frequency [35].…”

“…Table 1 shows that the activation energy value for a particular frequency above 1 MHz is in the range of 0.02-0.03 eV, whereas for lower frequencies below 1 MHz, the value is greater (0.04-0.07 eV). At low frequencies, charge carriers are thought to travel a great distance and are restricted to a potential well at high frequencies [27,30].…”

This article presents the investigation of dielectric and impedance spectroscopic properties of an organic product of 3-nitrophenol -2,4,6-tri amino-1,3,5- triazine (3NPTAT) single crystal, synthesized from melamine and m-nitrophenol. Comprehensive dielectric studies and charge transportation properties of the grown 3NPTAT crystal are given. The dielectric characteristics of the specimen were carried out in the frequency range of 50 Hz and 5 MHz at different temperatures, namely, 313 K, 333 K, 353 K, and 373 K. From the spectra, it was observed that the slowdown occurs at low temperatures, and the hopping mechanism takes place based on localized charge carriers. The impedance spectroscopic results indicate that there is a single relaxation process that occurs at high frequencies. The variation detected in the material properties of 3NPTAT corresponding to the temperature and frequency has been discussed in detail.

The semiconductor industry flourished from a simple Si-based metal oxide semiconductor field effect transistor to an era of MOSFET-based smart materials. In recent decades, researchers have been replacing all the materials required for the MOSFET device. They replaced the substrate with durable materials, lightweight materials, translucent materials and so on. They have came up with the possibility of replacing dielectric silicon dioxide material with high-grade dielectric materials. Even then the channel shift in the MOSFET was the new trend in MOSFET science. From the bulk to the atomic level, transistors have been curiously researched across the globe for the use of electronic devices. This research was also inspired by the different semiconductor materials relevant to the replacement of the dielectric channel/gate. Study focuses on diverse materials such as zinc oxides (ZnO), electrochromic oxides such as molybdenum oxides (including MoO3 and MoO2) and other binary oxides using ZnO and MoO3. The primary objective of this research is to study pulsed laser deposited thin films such as ZnO, MoO3, binary oxides such as binary ZnO /MoO3, ZnO /TiO2 and ZnO/V2O5 and to analyse their IV properties for FET applications. To achieve the goal, the following working elements have been set: investigation of pulsed laser deposited thin film of metal oxides and thin film of binary metal oxide nanostructures with effects of laser repetition and deposition temperatures.
