Annotation The paper critically reviewed experimental data and their theoretical explanations related to the change in conductivity of the various silicon structures arising from the adsorption of ammonia molecules. We performed quantum-chemical calculations to assess the possibility of the appearance of electronic conductivity by NH3 molecule protonation on the native Si oxide surface. Our calculations provide a full explanation of the experimental results on the subject recently obtained.
