Following publication of the original article [1], some errors were identified by the authors, which were not observed during proof reading.
- The authors have added additional scale values even in the presence of measured (real) scale bar and line resolution on SEM images to make them obvious on the real (raw) images presented in Fig. 3(g–i) and similarly, in Fig. S7. However, they would like to have SEM images only with measured (real) scale bar and line resolution on real (raw) images in Fig. 3(g–i) and Fig. S7 in order not to mislead the scientific society and the young researchers in this field.
- The scale of EIS on x-axis and y-axis in Fig. 5(c–d) and Fig. 6(a–b) has been mistakenly written as Ω cm^−2^, while the correct unit is Ω cm^2^. Unit and scale are corrected. The authors would like to remove the indication of fitted curve from Fig. 5(c–d); similarly, Fig. 6(a–b) had no fitted curve indication in published version.
- There is a typo error in the value of Q1 at 550 °C in Table 3, where the correct value is 5.97E-4 instead of 5.97E-14. The correct value of n is 6.73E-01 instead of 6.73E-02 at 500 °C in Table 3.
- The authors have identified a wrong funding number (51736006) in the funding source in the acknowledgments section; they want to remove it.
The updated Figs. 3, 5, 6 and Table 3 have been provided in this correction. The Acknowledgements and Supplementary file have been updated.
