a,b, Cross-sectional TEM images of the sample (1), after being washed with water to remove the top pCN layer. Three different spots were investigated, marked with red stars in insets; sampling position 8 (a, left), 10 (a, right), and 6 (b) as in Fig. 1e. The underlying aCN layer with the thickness of < 2 nm was visible in all three areas. However, in position 6 (b), the pCN residue was observed. Please see Supplementary Note 1 for details.
