Charge transport in anodic TiO2 nanotubes studied by terahertz spectroscopy
Original language description
We report on the photoelectrochemical and terahertz measurements, of the charge transport properties of 1 μm thick self-organized TiO2 nanotube layers, prepared by the anodization of titanium. We provide evidence regard-ing the complexity of electron transport, and dynamics in the nanotubes. Shortly after photoexcitation, charge mo-bilites in amorphous and crystalline nanotubes are similar, but still lower compared to the bulk anatase. The mobili-ty subsequently decreases due to trapping-detrapping processes. The recombination rate in anatase nanotubes is much slower than in the amorphous ones, enabling the material to reach an internal photon to electron conver-sion efficiency exceeding 60 %.
