Left column (a, d, g, j, and m) shows the cross-sectional TEM images of five different samples. The central column (b, e, h, k, and n) shows the CAFM current maps at 0.5 V, and the right column (c, f, i, l and o) shows 100 I–V curves for each sample collected at different positions of the sample (in a matrix of 10 μm × 10 μm).
