Figure 2From: Analysis of oxygen vacancy in Co-doped ZnO using the electron density distribution obtained using MEMPowder XRD patterns and Rietveld refinement results. Powder XRD patterns (black lines) and Rietveld refinement results (red circles) of ZnO, Zn0.99Co0.01O, Zn0.95Co0.05O, and Zn0.9Co0.1O samples. The differences between the XRD patterns and Rietveld refinement results are indicated by the lower blue lines. The green bars provide the calculated Bragg peak positions.Back to article page
