Figure 5From: AAO-assisted synthesis of highly ordered, large-scale TiO2 nanowire arrays via sputtering and atomic layer deposition TEM images of the AAO template coated with TiO 2 using ALD. (a) Cross-section of the TEM samples. (b, c) HR-TEM images of the anatase TiO2 (region 1), AAO (region 2), and Al substrate (region 3). (d-f) The FFT patterns for regions 1, 2, and 3, respectively.Back to article page
