Figure 2From: Anisotropic epitaxial ZnO/CdO core/shell heterostructure nanorodsTEM bright field image of the ZnO/CdO nanorod and the corresponding X-ray mapping. Cd Kα (red) and Zn Kα (blue) clearly show the formation of core/shell heterostructure. The peak labeled with asterisk is CuK peak originating from the TEM grid.Back to article page
