Morphological characterization of the metal (Au, Cu)-coated nb-Si electrodes. Cross-sectional SEM images of the (a) Au-coated and (b) Cu-coated nb-Si electrodes showing where the elemental maps were obtained and corresponding element mapping images of Au, Cu, O, and Si for metal (Au, Cu)-coated nb-Si electrodes. The upper right images of (a) and (b) show the summarized elemental signals.
