      abstract     = {Photoelectrochemical hydrogen production from solar energy
                      and water offers a clean and sustainable fuel option for the
                      future. Planar III/V material systems have shown the highest
                      efficiencies, but are expensive. By moving to the nanowire
                      regime the demand on material quantity is reduced, and new
                      materials can be uncovered, such as wurtzite gallium
                      phosphide, featuring a direct bandgap. This is one of the
                      few materials combining large solar light absorption and
                      (close to) ideal band-edge positions for full water
                      splitting. Here we report the photoelectrochemical reduction
                      of water, on a p-type wurtzite gallium phosphide nanowire
                      photocathode. By modifying geometry to reduce electrical
                      resistance and enhance optical absorption, and modifying the
                      surface with a multistep platinum deposition, high current
                      densities and open circuit potentials were achieved. Our
                      results demonstrate the capabilities of this material, even
                      when used in such low quantities, as in nanowires},
