aOne found that with an increase in ionic radius,the sintering temperature needs to be elevated continuously so that the doping ions gain enough energy to enter the Ti site of the BO6 octahedrons skeleton,and that the phase transition becomes morediffused, as observed for Ce4+-doped BaTiO3 [...
Owing to its similar d-electron configuration and oxide structure but relatively larger ionic size as compared with Ti4+, the doped single Zr4+ ion induces a strained effect without breaking the original TiO2 structure, which, in turn, enhances the formation of oxygen vacancy and subsequently bi-...
Unlike GZO thin films, TiO2-doped ZnO (TZO) exhibits Ti4 + (ionic radius: 0.68 Å) substitution for Zn2 + (ionic radius: 0.72 Å) ions; thus, each Ti atom acts as a donor that provides two extra free electrons and further improves thin-film conductivity (Sang et al., 2001...

Value of lattice parameters of all samples obtained from Rietveld refinement initially decreases with Ti-doping up to CSO5 and then slight increases for CSO7, due to difference in ionic radius between Ti4+(0.61 angstrom) and Sn4+(0.69 angstrom) and surface defect respectively. Using SEM, an ...
The decrease in lattice parameter is based on the smaller ionic radius of the substituted ions Ni2+ and Ti4+ than Fe3+ ionic radius. Molar magnetic susceptibility χM was measured using Faraday's method as a function of temperature from 300K to 650K, and the calculated magnetic constants ...
Ti4+ has a radius of 0.68 Å, which is smaller than that of Zn2+, 0.74 Å. When titanium atoms are doped into a ZnO lattice, they act as donors by providing two free electrons, thus increasing the free carrier concentration and decreasing the resistivity. Furthermore, ZnO films doped...
