Erratum Efficient solar energy conversion of TiO₂ nanotubes produced by rapid breakdown anodization – a comparison [Phys. Status Solidi RRL 1, No. 4, 135–137 (2007)]

Abstract There is an error in the scale bar of the inset of Fig. 1b in the original manuscript. The corrected figure is presented here in Fig. 1. As the originally used figure (see Fig. 2a here) was not very representative for TiO₂ nanotubes grown under the described conditions we now provide a more representative picture (Fig. 2b) confirming an average thickness of ∼2.5 µm (as given throughout the paper). No statement or other scientific content of the article is affected by this correction. (© 2011 WILEY‐VCH Verlag GmbH & Co. KGaA, Weinheim)
