The dc resistance of layered material CuFeTe2 responds to oxygen concentration by intercalation. We have investigated oxygen response of the impedance in the frequency range of 20 Hz to approximately 1 MHz. From analyzing by the complex impedance plot, it has been found that the ac equivalent circuit parallel and perpendicular to the sintered sample surface represents a resistance R∥, and the parallel circuit of a resistance R⊥ and a capacitance C⊥, respectively. The R⊥ has been also found to linearly respond to the oxygen concentration at room temperature.
