Table 1 Reliability factors of ZnO and ZnCoO samples

From: Analysis of oxygen vacancy in Co-doped ZnO using the electron density distribution obtained using MEM

Sample	R _I (%)	R _F (%)	a (Å)	Δg _O (%)
ZnO	1.473	0.731	3.24989	-
Zn_0.99Co_0.01O	1.066	0.605	3.25084	−0.39
Zn_0.95Co_0.05O	0.942	0.509	3.25120	2.03
Zn_0.9Co_0.1O	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.
