Résumé

Local pH change at n-GaAs cathodes was determined quantitatively by in situ infrared spectroscopy under conditions where diffusion of H_(aq) ⁺ toward the surface is rate limiting. A shift of the near-surface pH from 2 to more than 12 was evidenced by a change of the dominant phosphate species from H₃PO₄ and H₂PO₄ ^- to HPO₄ ^2- and PO₄ ^3-.
