title: Effect of heat treatment on phase transition of nanotubular titanium oxide arrays.
abstract: The purpose of this study was to investigate the effects of heat treatment on the cystallinity of titanium nanotubes. The titanium nanotubes had diameters ranging from 90-95 nm, lengths between 400-500 nm, and thicknesses of 11 nm. After heat treatment at high temperatures, the diameter and length of the nanotubes decreased, whereas the thickness increased. The titanium nanotubes exhibited amorphous + anatase phases at 300 degrees C, anatase + rutile phases at 500 degrees C and a rutile phase at 800 degrees C.
