Beschreibungen/Notizen

• We report on the remarkable stability of unmodified, epitaxially grown GaAs photocathodes during hydrogen evolution at -15 mA cm super(-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.
