Tailoring the charge carrier dynamics in ZnO nanowires : the role of surface hole/electron traps
Post-fabrication thermal-annealed ZnO nanowires (NWs) in an oxidizing (or a reducing) ambient were investigated using transient photoluminescence and X-ray photoelectron spectroscopy. Our findings reveal an ultrafast hole-transfer process to the surface adsorbed oxygen species (e.g. O2-, ) occurring...
