Abstract

The influence of the adsorption of methane and oxygen on the current-voltage characteristics of metal/porous silicon-ferromagnetic metal/crystalline silicon heterostructures has been studied. A qualitative model is proposed that explains the obtained results. It is established that structures based on the silicon-porous silicon system can be used to create methane sensors capable of detecting this gas on the background of atmospheric air at elevated temperatures.
