  • Patent number: 8613901
    Abstract: A titanium oxide nano tube material is configured so that crystal grains of a nano tube has a crystal structure oriented with the [001] direction of a tetragonal crystal system as a preferred direction. FWHM (Full Width at Half Maximum) of a rocking curve with respect to the (004) plane peak is 11.1 degrees to 20.3 degrees. The titanium oxide nano tube material has excellent photoelectric characteristics since the crystal grains of the nano tube are oriented with the (004) plane or the [001] direction of a tetragonal crystal system as a preferred direction.
