## Abstract The present work investigates the influence of different annealing treatments on the photoresponse of electrochemically formed TiO~2~ nanotubes. The βas preparedβ TiO~2~ nanotube layers have an amorphous structure and show a comparably low photocurrent magnitude. Annealing the tubes in
Auger depth profiling was used to determine the local film thickness of a thin anodic oxide grown on a polycrystalline Ti substrate. The oxide thickness was studied as a function of substrate crystallography and final growth voltage. These results were related to local photocurrent measurements obta
