    • Because the rapid decrease in φ of the ITO surfaces oxidized and chemically modified afterward was observed in air within lOh, we measured initial values of φ and CA within 20 min. In addition, φ was calibrated by comparing observed values of contact potential difference (cpd) on the modified ITO surfaces with the cpd value observed on HOPG.14 For average cpd measurements with a Kelvin probe force microscope, 15 gold coated AFM tips chemically modified with decanethiol were used as previously.80

    • From the view point of proportionality to surface concentrations XPS was considered to be more ideal, but the φ (t) measurements were found to be preferable for kinetics from their reproducibility. For Cl-S, the kinetic analysis was difficult because of small Δφ (t, The much higher degradation rates observed in water than in air are partially due to slight solubility of ITO in water see M.
