Donor-acceptor co-doped TiO2-based materials have attracted consideration attention because of their excellent dielectric properties, however, the effect of different acceptor ions on the dielectric properties of TiO2 single crystals has been the subject of little study. In this paper, (Nb0.5A0.5)0....
