“…This deals with the increase in orientation polarization, which leads to an increase in dielectric constant. [22][23][24][25][26][27][28][29][30][31][32][33] The mobility of charge carriers increases due to increased temperature. This case causes an increase in the dielectric loss.…”

Dielectric, conductivity, and modulus properties of a metal oxide semiconductor (MOS) capacitor with zinc oxide (ZnO) interlayer produced via radio-frequency magnetron sputtering were investigated using admittance spectroscopy measurements. Frequency and temperature dependence of the complex dielectric permittivity (*='-i''), dielectric loss factor (tan ), ac conductivity (ac), and complex electric modulus (M*=M'+iM'') were studied in temperature interval of 100-400 K for two frequencies (100 and 500 kHz). While the dielectric constant (') and loss ('') value increase as the temperature rises, their values decrease as the frequency rises. The increase in ' and '' is explained by thermal activation of charge carriers. Also, the ac value increases both frequency and temperature increase. The thermal activation energy was determined from slope of Arrhenius plot.

“…ZnO is inexpensive, handy, nontoxic, biocompatible [9], biodegradable [10], non-volatile, and the most biosafe semiconductor material [9]. It is widely used for numerous applications such as gas sensors [11], biosensors [12], drugs, cosmet-ics, storage, optical and electrical devices, solar cells [13], and biomedical applications [14][15][16][17]. To deposit ZnO thin film, several methods have been often used such as chemical vapor deposition [18,19], pulsed laser deposition [10,20], atomic layer deposition (ALD) [21,22], spray pyrolysis [13], RF magnetron sputtering [23,24], plasma spraying [25], dipcoating method [26], electron beam (e-beam) evaporation [27], chemical bath deposition [28], chemical oxidative polymerization [29], plasma electrolytic oxidation (PEO) [30], electrophoretic deposition (EPD) [31], and sol-gel [32], etc.…”

This investigation aims to improve the properties of 304 L stainless steel (SS) substrates for use in corrosion, mechanical, and biomedical applications by depositing ZnO thin films. The ultrasonic spraying technique was used to prepare ZnO thin films with depositional times of 1, 4, and 9 minutes. XRD and Raman studied the surface characteristics of ZnO samples. XRD analysis revealed a hexagonal structure with an average crystallite size of 22 nm for ZnO. Indentation nano measurements indicated an increase in the hardness of the films examined. To determine the type of conductivity and estimate the charge carrier density, potentiodynamic polarization, electrochemical impedance spectroscopy (EIS), and Mott-Schottky analysis were performed. The thin film deposited for 9 minutes was found to be the most effective in improving corrosion resistance.
