Figure 2From: Fabrication and ultraviolet photoresponse characteristics of ordered SnO x (x ≈ 0.87, 1.45, 2) nanopore films FE-SEM images of the AAO templates, ordered Sn and SnO x nanopore films. (a) top view of the alumina template prepared by a two-step anodization method; (b) cross-section view of the resultant highly ordered nanochannel alumina template; (c) ordered Sn nanopore film prepared at room temperature with P = 30 W and t = 3 min. (d, f) the top images of the ordered SnO x nanopore films prepared at different annealing temperatures (350°C, 450°C, and 550°C, respectively).Back to article page
