Popis:	A unipolar resistance switching (URS) Pt/NiO/Pt thin film structure was successfully deposited by sputtering. Each state was analyzed by using impedance spectroscopy. The equivalent circuit of the pristine state consists of resistor-capacitor parallel circuit. The low-resistance state could be described by using a single resistor. The high-resistance state comprised parallelly-connected resistor and constant-phase element, plus a serial inductor. Our results are in good agreement with a model for the formation/rupture of conducting filaments in the URS phenomenon.
