Fig. 6From: Improving Morphological Quality and Uniformity of Hydrothermally Grown ZnO Nanowires by Surface Activation of Catalyst LayerPotential difference ΔEp for different activation processes. Potential difference between the cathodic and anodic peak currents (ΔE p) measured right after activation and 1, 2, and 3 weeks later for the different activation processesBack to article page
