Description
Summary:The consideration of available gas-analyzers and materials for their fabrication has shown that they are not efficient for ecological control. In the fabrication of sensors, inorganic and organic semiconductors and biological membranes are used. Sensors made of inorganic semiconductors have high service life, but low selectivity. Biosensors have high selectivity, but low service life. Organic semiconductor sensors have high selectivity and fair service life, but high inertia. The effect of the film thickness, polymorphic modification, and barriers on the parameters of gas-sensitive organic structures is analyzed.
