摘要：

This paper discusses the preparation and properties of gas detectors based on "porous silicon-nickel ferrite" nanocomposites. Impedance spectroscopy was used to measure sensitivity to ethanol and isopropanol vapours in the presence of an alternating electric field. The results were interpreted with the help of an equivalent electrical circuit. In the analysis of the resistive-capacitive properties in the equivalent circuit a constant phase element was used.
