Abstract: 
We investigate the transfer of photoexcited charge carriers from GaP and GaNP nanowires to an electrolyte by bias-dependent photocurrent and electron paramagnetic resonance experiments using 5,5-dimethyl-1-pyrroline-N-oxide as a spin trap. The results of the latter show that hydroxyl radicals are created over the entire applied bias range from -1000mV to +1300mV by hole transfer. In contrast, the photocurrent changes from cathodic to anodic at the open circuit potential of the three-electrode setup with the nanowire sample acting as the working electrode. The experiments show that the photoelectrochemical response of GaNP nanowires is significantly stronger compared to that of the GaP nanowires. Published by AIP Publishing.
