Fig. 3: Enhancement in proton conductivity versus MIR irradiation intensity.
From: Mid-infrared light resonance-enhanced proton conductivity in ceramics
Δσ/σ for (a) bulk (orange) and (b) GB (turquoise) versus p controlled by adjusting the distance between the sample and MIR light source (d). The sample was maintained at 160 °C. Shadowed areas in (a) and (b) illustrate the 95% confidence band of the fitted curves. Comparison of Δσ/σ for (c) bulk and (d) GB observed in the experiments (closed circles) and estimated with the radiative heating effect (open circles connected with dashed line). The error bars in (a–d) incorporate standard deviations from three parallel measurements and fitting errors per sample across three samples prepared using the same method. Source data are provided in the Source Data file.
