The influence of
chemical etching and preliminary cathodic and anodic polarization on the
stationary electrode potential of a Hg3In2Te6
electrode has been investigated in various acidic solutions with different
pH-values. It is shown that In3+ ions govern the process of
formation of a double electric layer at the interphase
semiconductor/electrolyte for electrodes submitted to preliminary chemical
etching and anodization, while Hg2+ ions play the leading role in a
similar process occurring on the electrodes after cathodic polarization.
