Open circuit potential as function of InN coverage. OCP as a function of time for the InN/InGaN electrode and Ag/AgCl reference electrode immersed alternately for 150 seconds in 0.1 and 1 M KCl aqueous solutions. The insets show the top-view (left-hand side) and cross-sectional (right-hand side) SEM images. The InN deposition amounts are (A) 0.25, (B) 0.5, (C) 0.8 and (D) 1.2 ML. The thickness of the In0.45Ga0.55N layer is 95 nm for all samples.
