Reliability factors of ZnO and ZnCoO samples
Sample | R I (%) | R F (%) | a (Å) | Δg O (%) |
---|---|---|---|---|
ZnO | 1.473 | 0.731 | 3.24989 | - |
Zn0.99Co0.01O | 1.066 | 0.605 | 3.25084 | −0.39 |
Zn0.95Co0.05O | 0.942 | 0.509 | 3.25120 | 2.03 |
Zn0.9Co0.1O | 0.776 | 0.414 | 3.25235 | 3.48 |
Reliability factors based on the Bragg intensity (R I) and structure factor (R F), lattice constants (a), and relative change in oxygen site occupancies (Δg O) of ZnO and ZnCoO samples. g O refers to the site occupancy at the oxygen atom in the Rietveld refinement.
