P-Doped SiO₂ Proton Conducting Films for Low Voltage Thin Film Transistors

“…The semicircle is formed at the high frequency range (10 5 Hz < f) and is related to the ionic conduction process in the bulk of the film. The straight line is present in the low frequency region (f < 10 5 Hz) and is attributed to the effect of blocking electrodes [10] . Based on the impedance spectra, the effective AC resistance of the sample is determined by fitting the data to an equivalent circuit model composed of two resistors R t , R a and a capacitor C. In this case, because the R a closes to infinite, so its complex impedance is defined as: Z=R t -j/(ωC).…”

Effect of different ion-aggregating structures on the property of proton conducting membrane based on polyvinyl alcohol

“…Then, the membranes were annealed at 70 1C for 12 h. The membranes were stored in a sealed bag under a dry environment prior to use. The thickness of these membranes was about 100 μm, which is the thinner one among the traditional PVA membranes (100-300 μm) [19][20][21][22].…”
