Alumina Template-Dependant Growth of Cobalt Nanowire Arrays
Figure 2
Cross-sectional FESEM images of sulfuric acid alumina templates grown at (a, b) 25 and (c) 15 V following the template etching in 2 M for 15 minutes and deposition of cobalt nw arrays by AC (50 Hz) treatment in a same as in Figure 1 solution at constant AC current density of 0.3 A and room temperature for: (a) 5, (b) 15 and (c) 60 minutes. (a, b) 18 m, ~28 and (c) 20 nm.
