摘要：

The photocurrent enhancement by HIO3 at the n-InP anode was studied by a combination of dc and optoelectrical impedance measurements. It was found that this enhancement is connected with the anodic dissolution of the semiconductor itself. A reaction scheme is proposed for the dissolution mechanism, involving two competing reaction pathways, ie a mixed chemical-electrochemical and a purely electrochemical one, each with chemically different decomposition intermediates.
