Colossal permittivity and low loss in (In0.5Ta0.5)0.1Ti0.9O2 ceramics with a stable temperature range of X9D

DFT calculations and giant dielectric responses in (Ni1/3Nb2/3)xTi1−xO2

“…1 The dielectric properties of various acceptor/donor co-doped TiO 2 systems have been elucidated through the EPDD concept. 1,23,28,29 The sole EPDD mechanism still lacks a clear explanation for the overall dielectric properties over a wide frequency–temperature range. Additionally, the internal barrier layer capacitor (IBLC), electron hopping, and surface barrier layer capacitor (SBLC) models are widely employed to elucidate the contribution to the dielectric response.…”
