Origin of the colossal permittivity of (Nb + In) co-doped rutile ceramics by wide-range dielectric spectroscopy

Searching for giant dipolar defects, suggested as the explanation of the colossal permittivity (CP) in (Nb + In) co-doped rutile, we have recently published (J. Appl. Phys. 119, 154105 (2016) and P...
