Formation of ‘single walled’ TiO2 nanotubes with significantly enhanced electronic properties for higher efficiency dye-sensitized solar cells.

The present work establishes a process for the anodic growth of self-organized TiO₂ nanotubes with a single-walled morphology. This yields not only a much more defined tube geometry but also provides a significant increase in properties and prospect for a wide range of TiO₂ nanotube applications. [ABSTRACT FROM AUTHOR]
