“…The average phase angle () of transparent electrodes is found around positive 0.6 at frequency 1 kHz as shown in Tables 1-4. Thus, the electrical results were confirmed by the optical study in our previous study [29]. The transparent electrodes were found to be resistant to corrosion before and after irradiation.…”

“…Unlike the resistance, the impedance includes not only the relative amplitudes of the voltage and the current, but also the relative phases. The real and imaginary parts of the dielectric constant of undoped and doped transparent electrodes were determined with respect to the photon energy in our research [29]. The real part of the dielectric constant was found to have negative values in UV-Vis-NIR range.…”

“…The magnitude of the negative dielectric constant and the resonance frequency are tunable by dopant type and doping concentration. In our previous study the real part values of SnO2 and SnO2:Sb electrode was found to have negative values so the material was said to have an inductive optical response [29]. The imaginary part of undoped and doped electrode was observed to have positive values before γ-irradiation; so the material has a resistive optical response [29].…”

The imaginary part of undoped and doped electrode was observed to have positive values before γ-irradiation; so the material has a resistive optical response [29]. Since the average phase angle  (angle between current and voltage) of transparent electrodes has positive magnitudes, this means the transparent electrodes have inductive behavior.…”

“…Irradiation with gamma ray is able to induce chemical reactions at any temperature in the solid, liquid, and gas phase without the need of any catalyst. Cobalt-60 and Cesium-137 are the most common forms of gamma sources used as a cold treatment of semiconductor materials [27][28][29].…”

This work reports a study of corrosion lifetime of transparent electrodes deposited on the microscopic glass substrate. A procedure was developed for obtaining the transparent electrode by spray method. The corrosion lifetime variation in the presence of 1.5 M NaOH medium chemically degraded at room temperature before and after gamma irradiation was determined by measuring the evolution of the structure, electrical and optical characteristics. The mean values of transmittance up to 25 month before and after irradiation were calculated 91% ±6% and 96±7%, respectively. The average value of resistivity after corrosion and age time after γ-irradiation was 0.016±9% Ω.cm and 0.017± 4% at 1.0 kHz. No significant changes observed for 27 hr corrosion and 25 month age time of the transparent electrodes in NaOH solution.
