Figure 1
Scanning electron microscope images of 40 V RT grown nanotubes annealed at (a, b) 125°C and (c, d) 450°C. The 2 μm scale bar is for (a, c) while the 500 nm scale bar is for (b, d). (e) X-ray diffraction patterns of the samples. indicates possible presence of carbon impurities after 125°C heating, while is a possible other titanium oxide form.
