An electric device for determining aeriform substances, made from a multi-layer structure with a layer of semiconductor material, a layer of organic material and a layer of metallic material, wherein the layer of semiconductor material has a crystalline structure, the layer of organic material has a coverage degree not greater than 1 and is made of a substance the molecules of which are self-sustaining in an ordered manner, are bound to atoms of the crystalline structure of the semiconductor and interact with said aeriform substance to be determined in the sense of modulating the barrier height of the junction within the multi-layer, and the layer of metallic material is permeable to the aeriform substance to be determined and is chemically inert towards it. |
