Cuprous oxide (Cu<sub>2</sub>O) is a promising material for solar-driven water splitting to produce hydrogen. However, the relatively small accessible photovoltage limits the development of efficient Cu<sub>2</sub>O based photocathodes. Here, femtosecond time-resolved two-photon photoemission spectroscopy has been used to probe the electronic structure and dynamics of photoexcited charge carriers at the Cu<sub>2</sub>O surface as well as the interface between Cu<sub>2</sub>O and a platinum (Pt) ...[more]
