Abstract

We report on the remarkable stability of unmodified, epitaxially grown GaAs photocathodes during hydrogen evolution at −15 mA cm−2 in 3 M sulfuric acid electrolyte. Contrary to the perception regarding instability of III–V photoelectrodes, results here show virtually no performance degradation and minimal etching after 120 hours.
