Figure 2From: Electric charging/discharging characteristics of super capacitor, using de-alloying and anodic oxidized Ti-Ni-Si amorphous alloy ribbonsAFM image (a) and corresponding SKPM image (b) for surface of de-alloyed and then anodic oxidized Ti-Ni-Si specimen. Lower profiles of (a) and (b) are height from valley bottom and electrostatic potential for probe with 0 eV along red lines in upper images, respectively.Back to article page
