Fig. 4: Temperature dependence of the proton conductivity and corresponding parameters with and without MIR irradiation.
From: Mid-infrared light resonance-enhanced proton conductivity in ceramics
Arrhenius plots of (a) proton conductivity (σT) and (b) characteristic frequency of the bulk and GB processes (ω). c Vibrational factor (Q = ω0exp(ΔS/kB)) of bulk (circle) and GB (triangle) measured with (red) and without (blue) MIR irradiation at 130–200 °C. The calculated Q and their errors are represented by dashed lines and shadowed areas. Comparison of the corresponding Ea (orange), σ0 (blue), and Q (green) of d bulk and (e) GB. Data in (a–e) are presented as mean values from three parallel measurements per sample across three samples prepared using the same method. The error bars in (a–e) incorporate the corresponding standard deviations and fitting errors. Source data are provided in the Source Data file.
