Embedding Transition-Metal Atoms in Zirconia:Binding,Magnetism,Impurity States
Binding energy,magnetism and impurity states of V,Cr,Mn,Nb,Mo,Tc,W and Re doped ZrO2 are calculated from density functional theory.The binding of dopant in lattice is correlated to the atomic size of dopant.100% polarization of conduction carriers suggests V,Mn,Nb,Tc and Re could introduce spin-polarized charge carriers into nonmagnetic ZrO2 efficiently to make the room temperature single-spin injectors.The localized states in the band gap from dopants could induce the redshift of absorption edge,thus enhancing photocatalytic activity of zirconia.
