Wide range dielectric and infrared spectroscopy of (Nb plus In) co-doped rutile ceramics
Original language description
It is argued that the colossal dielectric permittivity reported by Hu et al. [Hu et al., Nat.Mater. 12, 821(2013)]has the same explanation as in the original colossal permittivity material CaCu3TiO4O12(CCTO), namely, a combination of the internal barrier layer capacitor (IBLC) and the surface barrier layer capacitor (SBLC) effects. The IBLC effect is caused by a microstructure consisting of insulating grain boundaries (thickness ˷ 1 nm and conductivity of ˷ 10-6 S/cm) surrounding interior regions of bulk conductivity approximately equal to 10-1 S/cm. The SBLC effect is the result of a depletion layer adjacent to the contacts approximately 100 nm thick with conductivity of 5*10-7 S/cm. The SBLC and IBLC effects give rise to dielectric relaxations in low-frequency and radiofrequency regions, respectively.
