Abstract

Dielectric properties and impedance spectroscopic studies of single phase Zn_1−xCo_xO (0 ≤ x ≤ 0.05) ceramics, synthesized by a pressure-less solid state reaction method, have been carried out to investigate the origin of colossal dielectric permittivity (CP), ε′ ∼ 10⁵, in a wide frequency (2 × 10¹–2 × 10⁶ Hz) range.
