Abstract
Evidence has been obtained for hot‐electron injection from illuminated p‐GaP photocathodes into nonaqueous electrolyte containing anthracene as the electron acceptor. The position of the conduction‐band edge at the electrolyte interface has been unequivocally established from Mott– Schottky plots in the dark and under illumination; no band‐edge movement occurs during the experiment. The observed supraband‐edge reduction of anthracene occurs with a hot‐electron energy of 0.9 eV.Keywords
