Figures 3 and 4 in the original article [e-J. Surf. Sci. Nanotechnol. 16, 36 (2018)] were inappropriately displayed. Correct figures are shown in this erratum. “Table 1” and “Table 3” that appear in the text on p. 39 in the original article should be replaced by “Table I” and “Table III”, respectively. The publisher found that they occurred during the production process. None of the corrections change any discussion and conclusions of the article.
