Annotation The paper critically reviewes experimental data and their theoretical explanations related to the change in conductivity of the silicon structures arising from the adsorption of NO2 molecules. Our quantum-chemical calculations showes that the adsorption of molecules of nitric oxide on hydrogenated silicon surface can lead only to the effective destruction of the dimer N2O4. Reversible increase in the concentration of free holes can be explained by adsorption of NO2 molecules on the surface hydroxyl groups.
